a93e725140 realtek: RTL93xx: Make use of correct ring size counters
The receive path of the RTL93xx SoCs is currently discarding packets
in software. Analysis gives the following explanation:

- RX ring size registers are setup with the full software ring size
- When packets are received the packet counter registers are increased
- After RX processing the counter registers are changed the wrong way
- From then SOC is allowed to receive more packets than software allows
- Overflow interrupts are fired
- As a reaction to that the software drops packets

Change the processing as follows:

- Setup ring size registers with a headroom of 2 buffers
- Decrease the counter registers with the real work done

With this change no more overflow interrupts occur because the SoC
disables the queues before they can overflow or hit a buffer that is
still owned by the CPU.

Benchmark from single stream iperf3 run, with server process running
on ZyXEL XGS1210 (RTL930x).

6fdff789cd realtek: Rename ZyXEL XGS1210-12 to XGS1210-12 a1
A new version of the ZyXEL XGS1210-12 has been discovered in
the wild. It includes at least two known hardware changes

- lan9/lan10 use RTL8221B instead of RTL8226
- lan9/lan10 use different SMI busses

Pave the new device the way by splitting the existing DTS.
According to the vendor website the models are named

- A1 (first version): not explicetly labeled
- B1 (second version): Label Rev. B1 on device

Rename the current OpenWrt device definition to A1 as it was
made for the first version. To stay compatible with older
installations, add the old device name to the list of

1a200ead4f realtek: rt-loader: add ROM uImage lookup (aka standalone)
The rt-loader currently only supports booting piggy backed lzma
compressed kernels. This requires a data layout where the kernel
directly follows the loader. That might not be sufficient for
more complex flash layouts.

Especially bootbase devices (like ZyXEL GS1920) will need some
kind of chain loading that needs to be explored yet.

Enhance the rt-loader as follows:

- Allow to build as standalone version
- In this case a flash start address is given
- During boot loader will search the ROM starting from that address
- If it finds a uImage this will be loaded into RAM
- Afterwards it will be decompressed to its load address
- While we are here add uncompressed uImage support

As always the implementation tries to be as simple as possible.

- uImage detection works without magics
- uImage will be loaded to highest possible memory address
- Documentation in Makefile has been adapted accordingly

Funny side fact: A standalone rt-loader can chain load a piggy
backed rt-loader from flash.

During bootup loader will show

d2beb6bdc4 realtek: rtl931x: Fix unsafe MAC_L2_GLOBAL_CTRL2 access
Registers must not be accessed in parallel by multiple drivers.
Read-modify-write operations are not atomic, and the result of parallel
access is undefined.

The MAC_L2_GLOBAL_CTRL2 register is essentially a pin configuration
register and is represented by a pinmux node in the devicetree.  Operations
on this register by the realtek,rtl838x-eth driver must therefore also be
reflected in the devicetree.

Since the MDIO sets used are board-specific, the pins must be enabled in
the board’s devicetree.  This can be achieved using the pinctrl properties
for the realtek,rtl83xx-switch.

    &switch0 {
    	pinctrl-names = "default";
    	pinctrl-0 = <&pinmux_enable_mdc_mdio_0>,
    		    <&pinmux_enable_mdc_mdio_1>;
    	....
    };

ea5a749311 realtek: rtl931x: Add LED Sync configuration
The pinmux-related registers on the RTL931X SoC family are spread across
various non-consecutive registers. It might be tempting to modify them
directly in a specific driver (SPI, LED, etc.), but this would cause issues
with parallel, non-locked read-modify-write operations, which are required
to update individual portions of these registers.

Instead, it is better to use the devicetree pinctrl properties to define
the correct configurations for the various operation modes.

One important setting here is the LED Sync bit. This allows the LED
controller to generate an additional positive edge on the `STCP`
("STore Clock Pin", also known as `RCLK`) of the LED shift register after
the actual content has already been shifted in using the normal shift
clock. The LED shift register is then expected to copy the content from the
shift register section into the storage registers, which act as the actual
LED output control. This functionality is available in, and commonly used
with, the SNx4HC595 family of shift registers.

To activate it, simply register it in the default state of the
"realtek,rtl83xx-switch" node:

    &switch0 {
        pinctrl-names = "default";
        pinctrl-0 = <&pinmux_enable_led_sync>;
        ....
    };

It would be nicer when this can be directly added to the led subnode. But
for this to work, `realtek,rtl9300-leds` must first be an actual driver
(known to the driver core).

a8e3bff523 realtek: convert access to RTL931x "even CMU" serdes pages
Currently the calculation for the CMU (even) SerDes works similar
to this pseudo code.

analog_backend_serdes = get_analog_serdes(frontend_serdes);
even_backend_serdes = analog_backend_serdes & ~1;
write_to(even_backend_serdes);

Because of the SerDes layout and frontend/backend mapping this can
be swapped to the following order with the same resulting Serdes.

even_frontend_serdes = frontend_serdes ~1;
analog_backend_serdes = get_analog_serdes(even_frontend_serdes);
write_to(analog_backed_serdes);

In the later example the frontend/backend mapping code is already
in our new functions. So swap the calculation logic and use the
new access functions. This allows to finally drop the old access
functions without mapping.

From now on all RTL931x SerDes functions will use a consistent
frontend view.

207ab9c36a realtek: convert access to RTL931x "digital 2" serdes pages

As the third step make use of these new functions whenever we want to

So the function conversion is as simple as this:

Old:
dsds = (sds - 1) * 2;

6802cd7f15 realtek: adapt RTl931x "digital 2" serdes page calculation
The more we step down into the SerDes deeps the more confusing it
gets. Nevertheless it is not to late to fix a wrong assumption.
Until now it seemed as if the frontend/backend SerDes mapping is
totally without intersection. This is not true.

The backend SerDes mapping is also dependent on the mode. Especially
the proprietary Realtek XSGMII mode stands out from all other
mappings. So fix the descriptions and the calculation of the third
page package (digital 2 aka XSGMII 2).

As it was not yet used it had no impact.

a3d681d7f5 realtek: XGS1210-12: convert RTL8226 PHYs to 2500base-x
We reached the point of no return. Upstream has gained the final
bits for the RTL8226 PHYs. That means.

- RTL8226 MAC side behaves like RTL8221(B)
- It's serdes no longer uses proprietary HSGMII (2.5G SGMII)
- Instead it dynamically switches between SGMII and 2500base-x

This (partly) solves one of the central henn/egg problems of the
Realtek target. To change the MAC/PHY interface mode both sides
need to have all bits in place to do so. But where to start if
so much needs to be done?

Now the PHY side has created facts and it mitigates a lot of
problems. All downstream HSGMII patches and coding can be dropped
in the future.

For now only adapt the only DTS that still maps PHYs to HSGMII.

6e416149d7 realtek: phy: drop use of mdio package functions
Our phy driver can handle some multiport phys (e.g. RTL8218B
or RTL8214FC). To access arbitrary ports some package access
functions have been defined. These were implemented in the
mdio bus with poor knowledge about the phy/mdio dependencies.
So they add unneeded complexity to the bus and the phy driver
must access these external functions directly.

Provide a new helper get_package_phy() that can derive any
phy device in a package from a given phy of that package.
Make use of this local helper and cut the mdio dependency.

While we refactor several firmware patching functions rename
the loop variables to "port" to better indicate what we are
working on.

fa1b362ae9 realtek: simplify RTL8214FC handling
Now that we have a get_base_phy() function a lot code of the RTL8214FC
handling can be cleaned up. To name a few:

- use phy_read/phy_write instead of mdiobus functions or the even worse
  phy_package_..._paged() helpers
- replace messages with phydev_info()
- remove if/else statements around copper/fibre handling

a1043fda8b realtek: phy: late phy package patching
Currently phy packages (like RTL8214x/RTL8218x) are patched and
initialized as soon as the first phy of the package is found.
In this situation the shared structure is not finalized because
devm_phy_package_join() has only been called for the first phy.
This is no issue as the patching directly hammers the bus addresses
for the follow-up phys.

In the future we want to simplify the package handling and allow
to access all phy_device structures from only one phy_device of
the package. With this we can use normal phy_read/phy_write.

Switch the probing logic to "late patching". With this we will
initialize the firmware of the package when the last phy of the
package has been found and thus the shared structure is complete.

Provide get_base_phy() as the first package helper that allows
to determine the first phy of the package from any other phy.

While we are here drop the shared structure that only repeats the
phy name and has no other use.

cb4603688b realtek: rtl930x: Add support for Plasma Cloud PSX10 Switch
The Plasma Cloud PSX10 Switch is a 8 + 2 port multi-GBit switch with
8x 10/100/1000/2500BaseT Ethernet ports and 2x SFP+ module slot.

Hardware:

- RTL9302C SoC
- Macronix MX25L25645G (32MB flash)
- Winbond W632GU6NB-12 (256MB DDR3 SDRAM - only 128 MB configured*)
- 2x RTL8224 4x 10m/100m/1/2.5 Gigabit PHY
- SFP+ 2x 10GBit slot
- IC+ IP8008 POE+ PSE controller

The switch is powered by 54 Volts 2.77A barrel connector. The internal TTL
serial connector can be used to access the terminal. Pins from 1: TX RX
(unused) GND.  Serial connection is via 115200 baud, 8N1.

A reset button is accessible through a hole in the front panel.

*) Only 128 MB of RAM are currently configured because there were
infrequent random memory corruptions detected when using memtester with a
256 MB DT configuration. This could also be reproduced with RTLSDK.

Installation
------------

* The device can be flashed by using sysupgrade command. Either from the
  original vendor firmware or using an initramfs (see "Debug")
* Connect serial as per the layout above. Connection parameters: 115200 8N1

7812d867b4 realtek: Introduce Plasma Cloud sysupgrade helper
Plasma Cloud devices use a dual-firmware regions/slots boot mechanism. On
APs, the u-boot is "intelligent" and checks the NOR/NAND partitions (kernel
+ rootfs) for corruption via "datachk". If validation fails, the bootloader
automatically switches to the fallback partition.

On Realtek-based switches, this "datachk" helper is not available.
However, the bootloader still supports two firmware regions/slots.

When flashing a new image, the "inactive" partition is written instead of
overwriting the active one. If no "inactive" partition exists but
"firmware1" is present, the bootloader always treats "firmware1" as
fallback. Only after a successful flash is the `u-boot-env` updated to
select the newly written partition.

On reboot, the bootloader loads the kernel from the new partition and
passes `mtdparts` information as the kernel cmdline. The Plasma Cloud
switch device tree does not override this with a `bootargs` property, so
the active partition layout is honored from cmdline.

Since offsets, sizes, and names of partitions match between the device tree
and cmdline (except the inactive slot), properties and nodes such as
`nvmem-cells` or `compatible` remain fully usable.

This mechanism also allows switching back to the old firmware slot.  For
example, if `firmware1` is currently active (`/proc/mtd` shows it), it can
be switched to slot 2 using:

    . /lib/upgrade/upgrade_dualboot.sh
    set_boot_part 2
    reboot

Firmware upgrades use standard `sysupgrade` tarballs, chosen for
compatibility with vendor images. In theory, one can switch between vendor
and OpenWrt with:

    sysupgrade -n /tmp/*-squashfs-sysupgrade.bin

Note: configuration files must not be preserved, as they are not compatible
with vanilla OpenWrt.

a4cbb44c1b realtek: convert access to RTL931x analog serdes pages
The RTL931x has 14 frontend and at least 26 backend serdes. Currently
the programming functions always need to determine the right backend
serdes from the given frontend serdes on their own.

We plan to provide a consistent serdes mapping to all callers as follows

Frontend SerDes  |  0  1  2  3  4  5  6  7  8  9 10 11 12 13
-----------------+------------------------------------------
Backend SerDes 1 |  0  1  2  3  6  7 10 11 14 15 18 19 22 23
Backend SerDes 2 |  0  1  2  4  6  8 10 12 14 16 18 20 22 24
Backend SerDes 3 |  0  1  2  5  6  9 10 13 14 17 18 21 22 25

frontend page               "even" frontend SerDes     "odd" frontend SerDes
page 0x000-0x03f (analog):  page 0x000-0x03f back SDS  page 0x000-0x03f back SDS
page 0x100-0x13f (XSGMII1): page 0x000-0x03f back SDS  page 0x000-0x03f back SDS+1
page 0x200-0x23f (XSGMII2): page 0x000-0x03f back SDS  page 0x000-0x03f back SDS+2

As a first micro step provide some helpers that simply operate on
frontend serdes and will determine the backend serdes on their own.

So rtmdio_931x_read_sds_phy() and rtmdio_931x_write_sds_phy() operate
on backend serdes. While rtmdio_931x_read_sds_phy_**new**() and
rtmdio_931x_write_sds_phy_**new**() operate on frontend serdes.

This is only an intermediate naming convention and will be cleanup
afterwards.

In a first step make use of these new functions whenever we
want to access the analog page. As the pages stay unchanged
in the new functions conversion is as simple as this:

Old:
asds = rtl931x_get_analog_sds(...)
rtmdio_931x_read_sds_phy(asds, ...)

New:
rtmdio_931x_read_sds_phy_new(sds, ...)

8c42e63a69 realtek: rtl93xx: fix incorrect destination port selection
When testing LLDP and STP, we observed that locally generated multicast
packets (e.g. LLDP, STP) were not restricted to the designated output
port(s). For example, when transmitting on `lan1`, the same packet was also
forwarded to other ports such as `lan2`.

Steps to reproduce:

1. Configure lldpd to use `lan1` in UCI and restart the service
2. Connect devices to `lan1` and `lan2`
3. Observe that the device on `lan2` still receives LLDP packets

The issue was caused by an incorrect `FWD_TYPE` setting in the TX CPU TAG,
which failed to enforce the selected egress port(s).

Fix this by updating the TX CPU TAG to set `FWD_TYPE` correctly, ensuring
that locally generated packets are transmitted only on the intended
port(s).

- SerDes read/write functions are moved away from the dsa driver
- All gets consolidated into the mdio driver (inside the ethernet driver)

A network interrupt may be received before the device is setup
properly. In this case NAPI structures are missing and __napi_poll()
will find a NULL pointer in n->poll. Avoid this by registering the
device after initialization is complete.

9037f815ee realtek: create central DTS macro include
The Realtek DTS's use several macros for convenient phy/port definition.
These are repeated for the RTL83xx targets and most are missing for the
RTL93xx targets. In the near future we want to add high port count
switches with 1GBit Ethernet for them too. As a preparation provide a
central include so the definition is only needed once and is available

44655c97bb realtek: backport upstream RTL9300 I2C driver
Backport/add all patches for the upstream RTL9300 I2C driver.

The upstream driver was added in 6.13 and was heavily based on our
downstream driver except for how the multiplexing behaviour is handled.
This driver was working fine with basic SFP operation on RTL930x devices
but there was no support for RTL931x though.

Major advantage over our downstream driver is: The multiplexing
behaviour is handled completely by the driver. Thus, there's no need for
a separate rtl9300-mux driver as we had it downstream. Moreover, this
simplifies the DTS of affected devices a lot since we can now move the
controller definition - which is in the DTS of each device so far - to
the base DTSI.

Currently pending patches are also included because the progress on
getting this upstream seems really slow right now, albeit upstream
maintainers may require several changes to the current state.

These include:
- patches fixing several issues in the driver
- patches doing a refactoring of the driver and adding support for RTL931x

See the commit messages included in each patch to have details on the
changes.

0724412c58 realtek: RTL838x harden ethernet driver against fuzzying
While checking setup routines for stability and completeness,
random RTL838x SoC I/O areas were intentionally overwritten.
As soon as L2_CTRL_1->FAST_AGE_OUT is set to 1, the system
stalls during bootup. Analysis shows that it loops endlessly
in rtl838x_hw_stop()

/* Flush L2 address cache */
if (priv->family_id == RTL8380_FAMILY_ID) {
	for (int i = 0; i <= priv->cpu_port; i++) {
		sw_w32(1 << 26 | 1 << 23 | i << 5, priv->r->l2_tbl_flush_ctrl);
		do { } while (sw_r32(priv->r->l2_tbl_flush_ctrl) & (1 << 26));
	}

This is exactly the same logic as in the vendor GPL. There
are no hints about possible timeouts or issues. The reason is
still unclear. Nevertheless harden the function for further fuzzy
tests. Do this by resetting the configuration value to its SoC
default.

Additionally convert some shifts to BIT() for better readability.

3e09991c07 realtek: switch Netgear NGE devices to rt-loader
The bootloader on these devices uses 0x81000000 as load address for the
compressed image. Since the kernel uses a load address 0x80100000, this
only leaves a space of 15 MiB for the uncompressed image. For larger
images, the compressed data starts to get overwritten, and at some point
the boot will fail:

    ## Booting image from partition ... 0
    ## Booting kernel from Legacy Image at 81000000 ...
       Version:      9.9.9.9
       Created:      2025-08-07  14:56:09 UTC
       Data Size:    6756645 Bytes = 6.4 MB
       Checksum ... OK
       Uncompressing ... LZMA: uncompress or overwrite error 1 - must RESET board to recover

Currently, initramfs images with default config are already over the
limit. And while they still happen to work regardless, adding additional
packages easily pushes the size so much that the boot fails.

Fix this by switching to rt-loader (which relocates the data to the
upper end of the RAM before decompression). The switch includes regular
kernel images to avoid this becoming an issue again in the future.

07a04d8485 realtek: RTL930x: reorganize mdio functions and SerDes register layout
The RTL930x mdio functions are scattered around the code. Relocate
them to the bus (still inside the ethernet driver). With this change
the phy identification looks into the proper registers. The SerDes
phy identifier (register 2/3) must be changed.

Additionally provide a consistent SerDes register access through the
mdio bus. Until now when a SerDes directly drives a SFP module there
is no clear rule of how to handle its register set that consists of
two parts:

- c22 phy registers 0-15 live in the fiber page (2) of the SerDes
- other SerDes specific registers exist in pages before and after

The mdio bus and other SerDes functions are a wild mix of directly
looking into page 2 or just using self defined methods to access
data.

Adapt the bus to the new consistent phy interface that mixes the
SerDes register set like classic Realtek phys do it.

- Use register 31 as page select (already in the bus)
- Always keep the common registers 0-15 in place and read fiber page
- Map the SerDes internal registers into the upper vendor specific
  registers 16-23 according to the page select register (31).

That gives a register mapping as follows:

+-----------------------+-----------------------+---------------+-------------+
| reg 0x00-0x0f         | reg 0x10-0x17         | reg 0x18-0x1e | reg 0x1f    |
+-----------------------+-----------------------+---------------+-------------+
| SerDes fiber page (3) | real SerDes registers | zero          | SerDes page |
| registers 0 - 15      | in packages of 8      |               | select reg  |
+-----------------------+-----------------------+---------------+-------------+

Example to make it as clear as possible.

SerDes registers on a RTL930x show

Page / Reg   | 0x00 0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0A 0x0B ...
-------------+----------------------------------------------------------------
0 - SDS      | 0C03 0F00 7060 7106 074D 0EBF 0F0F 0359 5248 0000 0F80 0000 ...
1 - SDS_EXT  | 0000 0000 85FA 8C6D 5CCC 0000 20D8 0003 79AA 8C64 00C3 1482 ...
2 - FIB      | 1140 6189 001C CA40 01A0 0000 0000 0004 0000 0000 0000 0000 ...

This translates to this phy layout

             | SerDes fiber registers  normal SerDes registers  zero     p.sel
Page / Reg   | 0x00 0x01 0x02 0x03 ... 0x10 0x11 0x12 0x13 ...  0x18 ... 0x1f

7cf7f7c6b9 realtek: add NAND targets for RTL93xx
Some known RTL93xx devices like the Linksys LGS328C or LGS352C are
NAND based. These require additional drivers and packages (e.g. UBI).
The current subtargets are already taylored down for devices with
only 16MB flash. Adding features that are not used will only make
the storage situation more complicated.

Add two new subtargets for RTL93xx that include the basic NAND, UBI
and MTD features. To achieve this do the following:

- Create new subtarget folders
- Copy the existing config and makefiles over
- Add the basic additional features
- Mark them as SOURCE-ONLY
- Add empty image makefiles
- Remove unneded NAND/MTD features from existing configs

feec7cf34d realtek: dsa: rtl83xx: flush scheduled work on removal
The workqueue items don't need to be processed directly when they are
scheduled. It can happen that they are simply processed at a much later
time. It is therefore necessary to ensure that all workqueue items of a
driver are no longer being processed before the driver (or structures of
this driver) are destroyed.

When skipping this step, the driver driver can cause a kernel Oops on
reboot.

Unfortunately, it is not recommended [1] to flush items out of the system
workqueue - simply because this can cause deadlocks. The driver itself must
have a private workqueue which is then flushed.

9ccfca3303 realtek: dsa: enhance pcs_get_state() for RTL93xx
Currently the SerDes driven SFP ports give strange ethtool readings
on RTL93xx devices. Especially duplex and speed are shown even if
no link is up and running. That leads to confusion because the MAC
reports arbitrary values.

Enhance the readout by refactoring the pcs_get_state() function.
Calculate speed/duplex/pause only if link is detected.

17822d5d18 realtek: use consistent definition in DTS for SFP(+) ports
We are slowly getting to the point where the mdio driver will be
carved out from the ethernet driver. Since the beginning it had
the feature to hand out SFP serdes as phys. So one can access
them from the phy driver. This will be kept during the final
migration and it even will provide a consistent interface for the
phy/serdes registers.

With this being done we need to identify how to handle the affected
ports in a generic way for all targets. Doing first things first,
this starts with a consistent DTS. Currently we have:

for RTL838x + Zyxel XGS1210:
  phy-mode = "1000base-x"
  managed = "in-band-status"
  phy-handle = ...

for all other RTL93x devices:
  phy-mode = "10gbase-r"
  managed = "in-band-status"
  pseudo-phy-handle = ...

Looking at the phylink kernel code one can see a nifty detail.
There is dynamic phy bringup depending on the mode.

int phylink_fwnode_phy_connect(struct phylink *pl,
                               const struct fwnode_handle *fwnode,
                               u32 flags)
{
        struct fwnode_handle *phy_fwnode;
        struct phy_device *phy_dev;
        int ret;

        /* Fixed links and 802.3z are handled without needing a PHY */
        if (pl->cfg_link_an_mode == MLO_AN_FIXED ||
            (pl->cfg_link_an_mode == MLO_AN_INBAND &&
             phy_interface_mode_is_8023z(pl->link_interface)))
                return 0;
        ...
}

Where 802.3z means 1000base-x or 2500base-x. Aligning this with
IEEE specs it means essentially:

- 10gbase-r defined ports with phy-handle must statically bring up
  a phylink from the beginning that immediately depends on a
  phy read_status() implementation.

- 1000base-x/2500base-x defined ports will dynamically bringup a
  phylink during link detection regardless of a phy-handle. So
  it usually runs at the moment when a SFP has been plugged in.

We currently still rely on a phy-handle but do not want to bring
up the phy immediately. Commit 4457c1eee4 ("realtek: rtl93xx:
support SFPs with phys") tried to fix exactly that error for
10gbase-r definied ports. Kernel shows "sfp sfp-p8: sfp_add_phy
failed: -EBUSY" in that case.

But it did it in the wrong way. It implemented a workaround by
introducing a DTS property "pseudo-phy-handle". Instead it
should have simply converted the DTS nodes to 1000base-x.

Revert the commit and fix the DTS with wrong definitions. From
now on we have a consistent SFP definition throughout all DTS
and targets.

Aside from the positive effect this setting has it is more or
less an arbitrary speed definition. When plugging in the SFP the
real speed will be choosen dynamically.

e0ba4cf086 realtek: rtl930x: move serdes functions over to mdio bus
The migration of the RTL930x mdio/serdes access functions over to the
mdio bus is a little more complicated than for RTL83xx. There are several
places where the serdes is accessed directly. So do it in two steps. With
this first step:

- use the rtmdio prefix for the serdes reader/writer functions
- move the functions over to the bus (inside the ethernet driver)
- Adapt all callers.

This is not only a copy/paste but the serdes access will be hardened too.
For this:

- put a mutex around the read/write functions because we have only
  indirect register access through a mdio style bus.
- Verify input values to avoid data mess.

afa4662ed0 realtek: RTL839x: reorganize mdio functions and SerDes register layout
The RTL839x mdio functions are scattered around the code. Relocate
them to the bus (still inside the ethernet driver).

Additionally provide a consistent SerDes register access through the
mdio bus. Until now when a SerDes directly drives a SFP module there
is no clear rule of how to handle its register set that consists of
two parts:

- c22 phy registers 0-15 live in the fiber page (2) of the SerDes
- other SerDes specific registers exist in pages before and after

The mdio bus and other SerDes functions are a wild mix of directly
looking into page 2 or just using self defined methods to access
data.

Adapt the bus to the new consistent phy interface that mixes the
SerDes register set like classic Realtek phys do it.

- Use register 31 as page select (already in the bus)
- Always keep the common registers 0-15 in place and read fiber page
- Map the SerDes internal registers into the upper vendor specific
  registers 16-23 according to the page select register (31).

That gives a register mapping as follows:

+-----------------------+-----------------------+---------------+-------------+
| reg 0x00-0x0f         | reg 0x10-0x17         | reg 0x18-0x1e | reg 0x1f    |
+-----------------------+-----------------------+---------------+-------------+
| SerDes fiber page (3) | real SerDes registers | zero          | SerDes page |
| registers 0 - 15      | in packages of 8      |               | select reg  |
+-----------------------+-----------------------+---------------+-------------+

Example to make it as clear as possible.

41b0340ff0 realtek: backport NAND driver for RTL93xx
RTL93xx devices have a NAND controller built in. Upstream already
has a driver in place. Include it downstream. Activate it in the
RTL93xx builds and disable it for the RTL83xx builds.

d802e6310a realtek: rtl931x: Support enable/disable SMI Polling for SerDes ports
During PHY matching, the SMI polling must be disabled to avoid conflicts
during the complex detection routine. Only after this finished, SMI polling
is allowed again.

This was implemented for all realtek families besides RTL931x.

b1597c9ad4 realtek: convert RTL838x toolchain to 24kc
The Realtek RTL838x devices have a MIPS 4Kec core. This has a very simple pipeline.
OpenWrt uses CPU_TYPE:=4kec to honour this and adds a dedicated toolchain with
some GB of extra space. There would be no problem if that toolchain would do what
it is expected to do. Looking at the build process one can see:

during kernel builds:
  ps -ef | grep mtune
  ... -march=mips32r2 -mtune=34kc ...

during package builds
  ps -ef | grep mtune
  ... -mips32r2 -mtune=4kec ...

So the kernel is optimized for the wrong cpu type while the applications fit fine.
Explanation for this is the generic/308-mips32r2_tune.patch. This forces kernel
builds to -mtune=34kc. Nevertheless everything runs fine since years on the RTL838x
targets.

It does not make sense to provide a dedicated 4kec toolchain for this mess. So
change the setup as follows:

- switch CPU type to mips24kc for RTL838x -> This drops one toolchain and saves space
- Add a RTl838x specific mtune=4kec patch -> Builds kernel with the proper setting

Downside is packages will be built with -mtune=24kc. So a look at a simple benchmark
should give insight if this has really a big impact. See numbers attached. To sum it
up in two sentences

- All non RSA benchmarks are within expectation
- RSA benchmarks show large deviations (before and after)

The normal usecase for these switches is definetly not a CPU intensive workload
so this is ok for now.

Before: kernel 6.12 (mtune=34kc) + apps (mtune=4kec)

13. Wait ~120 sec to complete flashing

Reverting to stock firmware:
 1. Prepare by downloading the stock firmware. Vimin doesn't have
    the firmware on their website, tested using firmware for shared
    hardware Nicgiga S100-0800S-M.
    Filename: vmlinux-nicgiga-S100-0800S-M-241126EN.bix

 2. Prepare TFTP server with an IP address "192.168.1.111"
 3. Connect your PC to Port1 on VM-S100-0800MS
 4. Power on VM-S100-0800MS and interrupt boot by pressing Esc
 5. Enable Port1 with the following commands

    rtk 10g 0 fiber1g (or fiber10g if 10GBase-*R, dac300cm for DAC cable)
    rtk ext-devInit 0
    rtk ext-pinSet 2 0

    Note: the last command sets tx-disable to low

 6. Download initramfs image from TFTP server

    tftpboot 0x82000000 <image name>

 7. Boot with the downloaded image

    bootm

 8. Under Management -> Firmware -> Upgrade/Backup, upload bix file.

ed7d62caf2 realtek: add support for Hasivo S1100W-8XGT-SE switch
This commit adds support for Hasivo S1100W-8XGT-SE switch.

Device specification
--------------------
SoC Type:	RTL9303
RAM:		Samsung K4B461646E-BYKO (512MB)
Flash:		Fudan FM25Q128A (16 MB)
Ethernet:	8x 10G via 2x RTL8264 PHY
LEDs:		2 LEDs, 1 power green, 1 system green
Button:		Reset
USB ports:	None
Bootloader:	Realtek U-Boot - U-Boot 2011.12.(3.6.6.55087) (Nov 13 2022 - 14:37:31)
Fan:            2 fans controlled by STC8G1K08 TSOP-20 microcontroller

Note: The fan appears to operate the same irrespective of the running
firmware. The STC9G1K08 is likely operating independently.

To explore the stock vendor firmware, there are 2 avenues to gain root
access. This is not necessary to install OpenWrt, but is here for
reference.

Root access via serial
----------------------
1. ctrl+t
2. password: switchrtk
3. press 's' for shell

Root access via SSH
-------------------
1. ctrl+t
2. password: switchrtk
3. sys command sh
4. log in with your username+password
5. ctrl+t
6. password: switchrtk
7. press 's' for shell

Credit to https://forum.openwrt.org/t/hasivo-switches/151758/174 for rooting instructions.

Installing OpenWrt
------------------
1. Connect to UART. UART requires soldering an RJ45 connector to the
   console footprint on the board. The header is on the top right of
   this image: 4d2ab97fad.jpeg
2. Set computer IP to 192.168.0.111.
3. Enter bootloader by pressing esc key during boot.
4. Enter password 'Hs2021cfgmg'.
5. Type 'XXXX'.
6. setenv bootcmd 'rtk network on; bootm 0xb4300000'
7. saveenv
8. rtk network on
9. tftpboot 0x84f00000 <openwrt-initramfs>
10. bootm 0x84f00000

Now you can copy over the sysupgrade image and install.

ec69736270 realtek: implement polling for hardware counters
Maintain 64 bit counters by polling the hardware counters and adding up
the differences. Polling needs to happen just often enough to catch
every single overflow.

As we now have non-overflowing counters now, we can safely calculate
composite counters without getting weird results on overflow. Use this
to follow RFC 3635 more accurately by mapping the hardware counters to
the proper counters, while taking into account hardware quirks as best
as possible.

e27e695978 realtek: use more specific APIs for ethtool stats where possible
The kernel offers several alternatives to get_ethtool_stats which allow
to report some stats in a more structured way. Use them where possible.

Ideally, we should follow RFC 3635 to translate the hardware counters to
the supported frame and octet counters. However, this is not feasible,
as some of the counters are 32-bit only (so it would produce incorrect
results as soon as one of them overflows).

831c1cd864 realtek: fix ethtool stats for RTL839x and RTL930x
The MIB registers contain different stats depending on the SoC, and for
RTL930x some stats are in an additional register.

Create separate MIB descs for each SoC to implement this. Also make
reading 64-bit counters more robust, by protecting against an overflow
of the lower 32 bits during the read.

RTL931x remains unsupported, because it uses a table and thus requires
a separate implementation.

While we are at it, rename structs/functions to use the rtldsa prefix.

21d3722c40 realtek: don't disable MIPS counter on secondary VPEs
After observation that timer interrupt 7 always fires on secondary VPEs
the counter was disabled in the startup code. This is a bad idea when
building the kernel with jitterentropy. To generate entropy it makes use
of function random_get_entropy(). On MIPS architecture this simply reads
the counter register on the current core. With a disabled counter it
always returns the same value and the entropy initialization stalls the
core if it runs on a secondary VPE. See backtrace

a3bfb67072 realtek: mdio: RTL838x: move functions over to bus
The mdio bus functions are still split between ethernet and dsa driver.
Before moving everthing out to a separate mdio driver we decided to
collect everything in the ethernet driver with the rtmdio prefix.
Take over the remaining RTL838x functions.

Remark: This is more or less a copy/paste with function renaming. As
there are still some consumers in the DSA driver the definitions and
inclusions must be flipped.

ded18a3683 realtek: dsa: enhance pcs_get_state() for RTL83xx
Currently the SerDes driven SFP ports give strange ethtool readings
on RTL83xx devices. Especially duplex and speed are shown even if
no link is up and running. That leads to confusion because the MAC
reports arbitrary values.

Enhance the readout by refactoring the pcs_get_state() function.
Calculate speed/duplex/pause only if link is detected. Additionally
add reporting of 10G for SFP+ on RTL839x.

9533e2e574 realtek: dsa: relax capability checks for 2.5G modes
The driver currently uses two checks to verify the capabilities. These
are ..._phylink_get_caps() and ..._pcs_validate(). For RTL930x these
must allow 2.5G modes. Enhance that as follows:

Add 2500BASEX to phylink_get_caps(). Sort the interfaces alphabetically
and rename the function to the new prefix. IMPORTANT REMARK! Until now
this function allowed the XGMII mode (10G only parallel interface) that
was somehow mixed with the Realtek proprietary mode XSGMII (10G SGMII).
Remove it to avoid further confusion.

Looking upstream pcs_validate() is used less and less. There are only
2 consumers left in 6.16 and the calling location reads:

	/* Validate the link parameters with the PCS */
	if (pcs->ops->pcs_validate) {
		ret = pcs->ops->pcs_validate(pcs, supported, state);
		if (ret < 0 || phylink_is_empty_linkmode(supported))
			return -EINVAL;

		/* Ensure the advertising mask is a subset of the
		 * supported mask.
		 */
		linkmode_and(state->advertising, state->advertising,
			     supported);
	}

There is no need for this additional check. Drop the functions.

963ee6ac3f realtek: avoid interrupt storm on mass packet receive
RTL83xx devices have two types of receive interrupts for each of its
8 rings. One for packet received and another for ring overflow. When
the switch is flooded with incoming packets the receive handler will
disable the packet receive notification but still keeps the overflow
notification enabled. While the receive path "slowly" processes the
received packets each new packet triggers the overflow IRQ again. The
device becomes unresponsive and eventually produces messages like:

6432b41180 realtek: rtl931x: fix setting number of leds per port
In rtl931x_led_init, the number of leds per port is not properly set. It
currently uses a hardcoded value of 1 which seems to be taken initially
from a specific device. This hardcoded value assumes any port always has
exactly two leds.

The RTL930x variant - rtl930x_led_init - does a better job at this. So
take it and use it for RTL931x too with the corresponding register.
While at it, rename the function to a proper naming scheme.

d2108c2c58 realtek: enhance RTL930x SerDes/PLL/CMU interoperability
The operating mode of a SerDes must be aligned with the attached PHY or
SFP module. That does not only require to change the protocol (e.g. SGMII,
10Gbase-R, ...) but also the speed (e.g. 1.25G). For this the SerDes must
be re-initialized properly.

- It must be taken into power down
- The PLL speed must be set
- Maybe the CMU (clock management unit) must be resetted
- The new mode must be set
- The state machine must be resetted
- The power must be reactivated

Until now this sequence is bugged. First the driver relies on a clean
setup from U-Boot (rtk network on) and second trying to to change mode
and PLL speeds does not work at all. And not to forget: Currently two
adjacent SerDes cannot drive SGMII/HSGMII at the same time. Fix this by
taking care about the right SerDes/PLL/CMU command init order.

P.S. This code is inspired by the work of Jan Hofmann, who tried to
enable parallel SGMII/HSGMII mode. The only missing bit was a proper CMU
reset sequence.

Until now the rt-loader only works on U-Boot driven devices where the
environment (e.g. coprocessor) is usually setup properly. Devices like
the ZyXEL GS1920 series use BootBase as start environment and skip
some of the basic initialization steps. rt-loader will fail in these
cases. Take care about the CP0 registers.

Additionally enhance the documentation of the printf implementation.

ccbff8bbdd realtek: add rt-loader (runtime loader)
The bootloader of many Realtek switches only supports gzipped kernel images.
With limited flash space that might get critical in future versions. For better
compression allow support for compressed images. For this a new loader was
developed. Several ideas have been taken over from the existing lzma loader
but this has been enhanced to make integration simpler. What is new:

- Loader is position independent. No need to define load addresses
- Loader identifies device memory on its own
- Loader uses "official" upstream kernel lzma uncompress
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/lib/decompress_unlzma.c
- Loader uses "official" UNMODIFIED nanoprintg that is used by several
  bare metal projects. https://github.com/charlesnicholson/nanoprintf

Compiled the loader ist just under 12KiB and during boot it will show:

rt-loader

6a1d7bf52b realtek: overwrite c22 polling unconditionally on RTL930x
During setup the mdio driver decides the polling mode of the 4 smi
busses depending on the DTS phy settings. This works as follows:

- set polling to c45 if at least one phy is ethernet-phy-ieee802.3-c45
- set polling to c22 if all phys are ethernet-phy-ieee802.3-c22

On RTL930x it is not possible to switch to c22 if uboot has set c45
before. Fix this by overwriting the bitfield properly. While we are
here:

- Sort variables according to kernel style (inverse christmas tree)
- Initialize fields properly with  = { 0 }
- Use GENMASK() for better readability
- Make use of RTMDIO_MAX_SMI_BUS

83880cd01e realtek: Use Otto timer on RTL931x
Until now the timer management on the RTL931x devices depends
on the MIPS default timer. Looking at the clock progress on
these devices one can see that it is totally off. It is running
at half the required speed (e.g. if 1 minute passes the date
command shows that according to the timers only 30 seconds have
elapsed). This is a mix from wrong DTS and bad startup code.

This is not only a cosmetic issue but has effects on every
delay operation inside the kernel. Switch RTL931x to the proven
Otto timer.

Tested on LGS352C based on RTL9311.

5703ca465c realtek: add dts helper for internal phy with serdes
Until now only the RTL930x devices make use of the following notation.

  phy8: ethernet-phy@8 {
    compatible = "ethernet-phy-ieee802.3-c22";
    phy-is-integrated;
    reg = <8>;
    sds = <3>;
  };

This indicates that the link is driven by a serdes directly without
external phy. As the devices have multiple serdes it must be clarified
what serdes is responsible for that port.

Nevertheless all other devices have the same requirements. E.g. RTL838x
usually drives port 24 from serdes 4 and port 26 from serdes 5. All this
currently works because the driver has a lot of hardcoded port/serdes
mapping.

Make the situation better by adding dts helpers that can describe the
topology as needed.

22854586c6 realtek: fix/add switchcore syscon nodes for RTL838x/RTL839x/RTL931x
The switchcore node is the central location that describes the Realtek switch
register addresses starting at 0x1b000000. It will be used by current and
future regmap enabled device drivers. The upstream MDIO driver already makes
use of it by calling syscon_node_to_regmap(dev->parent->of_node);

In the current DTS base we have 3 issues that should be fixed:

- rtl838x.dtsi has a length of 0x20000 instead of 0x10000
- rtl839x.dtsi has a length of 0x20000 instead of 0x10000
- rtl931x.dtsi has no switchcore node at all

Align these mismatches with the "good" RTL930x template.

0bd5d5f748 realtek: rtl931x: fix I2C sda pin
The drivers for I2C bus and mux for RTL931x have an incorrectly defined
SDA0 pin number, causing an error with correct pin numbers specified in
the device tree.

Using the `show tech-support board` on the vendor firmware of a Netgear
MS510TXM shows the correct pin numbers but they don't work with the
drivers. So fix this.

24d9fdff2e realtek: rtl931x: add missing function reference for l2_hash_seed
Add missing function reference for the l2_hash_seed call in rtl931x_reg
in the rtl83xx DSA driver part.
While at it, rename the referenced function to proper naming convention
and simplify its content.

The missing reference causes a hard crash after a short time (on
MS510TXM) because the driver assumes the reference always exists.

acd7ecc9ed realtek: add new i2c-gpio-shared driver for shared SCL lines
Some Realtek switches have been designed with I2C busses that share a
single SCL line. The clock line is used for 2 or more busses. This cannot
be used with the standard i2c-gpio driver that relies on distinct SDA
and SCL pairs.

Provide a derived i2c-gpio-shared driver that can be used instead. This
driver can handle up to 4 busses with only a single clock line.

6af9476b8a realtek: Add support for Zyxel XGS1210-12 Switch
The Zyxel XGS1210-12 Switch is a 10 + 2 port multi-GBit switch with
8 x 1000BaseT, 2 x 10/100/1000/2500BaseT Ethernet ports and
2 SFP+ module slot.

Hardware:
- RTL9302B SoC
- Macronix MX25L12833F (16MB flash)
- Nanja NT5CC64M16GP-1 (128MB DDR3 SDRAM)
- RTL8231 GPIO extender to control the port LEDs
- RTL8218D 8x Gigabit PHY
- RTL8226 2x 10m/100m/1/2.5 Gigabit PHY
- SFP+ 2x 10GBit slot

Power is supplied via a 12V 1.5A standard barrel connector. At the
right side behind the grid is UART serial connector. A Serial
header can be connected to from the outside of the switch trough
the airvents with a standard 2.54mm header.
Pins are from top to bottom Vcc(3.3V), TX, RX and GND. Serial
connection is via 115200 baud, 8N1.

A reset button is accessble through a hole in the front panel

At the time of this commit, all ethernet ports work under OpenWrt,
including the various NBaseT modes, SFP+ slots are supported with i2c bus.

Installation
--------------
* Connect serial as per the layout above. Connection parameters: 115200 8N1.
* Navigate to 'Management' in the OEM web interface and click on 'Firmware upgrade'
  to the left.
* Upload the OpenWrt initramfs image, and wait till the switch reboots.
* Connect to the device through serial and change the U-boot boot command.
  > fw_setenv bootcmd 'rtk network on; boota'
* Reboot, scp the sysupgrade image to /tmp, verify the checksum and flash it:
  > sysupgrade openwrt-realtek-rtl930x-Zyxel_xgs1210-12-squashfs-sysupgrade.bin
* Upon reboot, you have a functional OpenWrt installation. Leave the bootcmd
  value as is - without 'rtk network on' the switch will fail to initialise
  the network.

Debug
------------
* Connect serial as per the layout above. Connection parameters: 115200 8N1.
* A tftp server is requiered, tftpd-hpa works well.
* Power the device, at U-Boot start rapidly hit Esc key to stop autoboot
* Enable network:
  > rtk network on
* Change ip address (default is 192.168.1.1):
  > setenv ipaddr 192.168.1.6
* Download initramfs:
  > tftpboot 0x84f00000 192.168.1.111:openwrt-realtek-rtl930x-Zyxel_xgs1210-12-initramfs-kernel.bin
* Boot loaded file:
  > bootm 0x84f00000

This prodecudre also apply to the sock firmware with the file XGS1210-12_V2.00(ABTY.1)C0.bix.

More information can be found on the page of XGS1250-12 as they share the same base.
