0d769903dd realtek: Indicate that RTL8231 LED ops can sleep
The RTL8231 LED driver is using the .brightness_set op, which according
to the documentation should not sleep. Since the RTL8231 is controlled
via an MDIO bus, this is not the case.

When using a non-offloaded LED driver such as netdev, this may currently
trigger kernel warnings:
    WARNING: CPU: 0 PID: 14 at kernel/time/timer.c:1754 call_timer_fn.isra.0+0x84/0x8c
    timer: led_timer_function+0x0/0x1d8 preempt leak: 00000100 -> 00000000

Switch to the .brightness_set_blocking op to indicate the operation
might sleep.

361c1107cb realtek: eth: merge decode_tag() for RTL93xx
rteth_930x_decode_tag() and rteth_931x_decode_tag() are basically
the same. The only difference is the port bitmask. Luckily on the
RTL930x devices the unused fifth bit is always zero and the mask
can be aligned with RTL931x. Take over the RTL931x reason debugging
for both targets.

0f5015fc5e realtek: pcs: rtl931x: set SerDes to off early
Set the SerDes mode to OFF early in the setup process to have a clear
starting point. This was part of the media handling before as a leftover
from the SDK code import. In the SDK, this function didn't only care
about applying some media settings but was also some kind of mode
setting for fiber modes.

be10ea16ac realtek: pcs: condense fiber media types
Right now we operate with distinct media types for fiber using different
speeds. This is more of a leftover from the SDK then it really makes
sense design-wise. The set_media function from the SDK did a lot more
than just setting some media-specific parameters. As part of
deconstructing this, also reduce the fiber types to a single media type
and handle the speed-agnostic parts based on the hw_mode for now.

This also drops the check for 100M speed around a block of writes. This
check has it's origin in SDK code where a switch statement just didn't
handle this case. However, the rest of the SDK doesn't handle this case
either. While the explicit 100M support isn't verified yet, there's no
need to keep that check.

7c7058b66b realtek: pcs: collapse DAC media types
So far we had separate media types for different DAC cable lengths,
equal to how the SDK defines them. However, this seems overengineered.
The types '_50CM' and '_100CM' are always treated equally, same for
'_300CM' and '_500CM'. Not only in the RTL931x code, but also the
RTL930x code usually just makes a distinction between short and long.
Thus, make that a bit cleaner by reducing the DAC type set to '_SHORT'
and '_LONG' with DAC cables < 3m being considered short and those with
>= 3m being considered as long.

beb57dbc6d realtek: pcs: rename port_media to sds_media
The term 'port media' was chosen due to how the code taken from the SDK
was organized. However, the SDK does a pretty good job at intermixing a
lot of things which cause confusion in the end. This also applies to the
media settings. To be correct, we do not really have port awareness in
the PCS driver (and probably shouldn't have) so we do not really deal
with a port's media. Instead, we set settings depending on what is
attached to the SerDes itself.

To fix this confusion, rename the enum, its fields and all usage from
'port_media' to 'sds_media'.

741ac49396 realtek: add support for Datto L8
Add support for Datto L8 with 8 copper ports.
POE+ support with 55W power budget.

Specifications:
---------------

    * SoC: Realtek RTL8380M
    * Flash: 32MiB Flash
    * RAM: 256MiB
    * Ethernet: 8x 10/100/1000 Mbps
    * PoE: 8x
    * Serial: UART 3.3V TTL logic, 115200 8N1
        * pinout: G(ND) R(x) T(x) V(cc)
    * Buttons: 1x Reset, 1x LED Mode (noop in OpenWrt)

Note: OpenWrt combines the stock dual firmware partitions
for more overlay capacity, however the OpenWrt image cannot
exceed 13504k

Installation:
-------------

> When connected to CloudTrax, the local management login will be disabled to prevent settings conflicts.

Ensure the switch does not have a working internet connection or the local
web management interface is disabled.

Go to the web management page of the switch (may require factory reset).
By default the switch will use DHCP to obtain an IP address.

The default login user is `admin` with password `0p3nm3$h!`

On the left menu, click "Management" and then "Dual Image" and ensure that
"Partition 0" is selected as the active partition. If it is not, select
"Partition 0" and click "Apply" to save changes.

Click on "Upgrade" in the top right of the web interface. Select the
Active boot partition to update. Select the OpenWrt file ending
in `-initramfs-kernel.bin` as the update file to upload.

Upload the file and follow the prompts to upgrade the firmware.

Reboot the switch from the web UI after the firmware update is completed.
Wait for OpenWrt to finish booting (~2 minutes)

Use SSH or the Luci UI (if available) to perform the sysupgrade.

Copy the sysupgrade file ending in `-squashfs-sysupgrade.bin` to the switch:
```
scp -O openwrt-realtek-rtl838x-datto_l8-squashfs-sysupgrade.bin root@192.168.1.1:/tmp/
```

SSH to the switch and run `sysupgrade`:
```
ssh root@192.168.1.1
$ sysupgrade -n /tmp/openwrt-realtek-rtl838x-datto_l8-squashfs-sysupgrade.bin
```

OpenWrt will be installed. Note that first boot after installing requires ~3
minutes for the JFFS2 overlay to be formatted. When the Power LED stops blinking
in the first boot after `sysupgrade`, JFFS2 formatting is completed.

----

Revert back to stock firmware:

You will need a tftp server and the original Datto firmware.

Download the firmware for the S8-L/L8 from Datto:
https://networkinghelp.datto.com/help/Content/kb/Networking/Switches/KB360023113291.html

Rename `s8-l_fw_01.03.24_180823-1639.bix` to `vmlinux.bix`,
put `vmlinux.bix` in the root directory of your tftp server.

Connect a serial console to the UART header and power on the switch.

Interrupt U-Boot by typing `pac` when you see
`Enter correct key to stop autoboot:`

Run the following commands:
```
setenv serverip <tftp_server_ip>
setenv ipaddr <ip_on_same_subnet>
setenv netmask 255.255.255.0
run rtkon
run update_linux
run update_linux2
reset
```

The switch will boot the Datto firmware.

316f41e310 realtek: dts: convert EXTERNAL_PHY() to PHY_C22()
The Realtek target currently uses two phy macros to simplify the
device dts.

- EXTERNAL_PHY() to denote a phy attached to the SoC
- INTERNAL_PHY() to denote an internal PHY (inside the SoC)

There is no benefit doing this. The topology around a port/phy is
well defined by the port macros. They link port, phy, pcs and even
leds. The only consumer of the attribute "phy-is-integrated" is
inside the dsa driver and that is being refactored.

As a first step define a new more meaningful PHY_C22() macro that
describes a c22 capable phy. This does not need to care about the
external/internal relation. To make it even more useful for the
RTL93xx targets with multiple mdio busses give it two parameters
PHY_C22(port_number, bus_address) where

- port_number is the absolute overall unique phy number
- bus_address is the location of the phy on the bus

For RTL83xx these two parameters will usually be the same. Instead
of three steps (inventing the macro, converting the consumers and
removeing the old macor) do a one-step conversion for the existing
EXTERNAL_PHY() macro.

f1f0572d1f realtek: dsa: remove redundant integrated phy attribute
The dsa driver currently has different attributes to denote what
hardware is around a port:

- phy_is_integrated: true if phy is not driven by a serdes
- phy: the type of the attached phy (e.g. 0=NONE, 2=RTL8218B, ....)
- pcs: link to a serdes pcs instance

This is somehow redundant and especially the phy type should be only
part of the phy driver and is not needed by the dsa driver at all.
Remove the redundancy by simply keeping a boolean attribute "phy" that
flags a phy driven port and can be used similar to the pcs (pointer)
attribute. With that the driver can check phy/pcs as follows:

- if (ports[i].pcs) -> port has a dedicated serdes
- if (ports[i].phy) -> port has a dedicated phy

That implemented, the "phy-is-integrated" attribute of a phy can be
removed from the dts. This will be a separate commit. As a side effect
the following (annoying) boot message for kernel 6.18 gets fixed.

78ffee0ed2 realtek: force in-band autoneg on XGS1250-12 A1 10G PHYs
In kernel 6.18, upstream added a change to the Aquantia PHY driver which
reports autoneg and inband capabilities as the PHY supports it, and
configures it accordingly in the PHY [1]. Due to how phylink works, it
then decides to turn off in-band signalling and prefer outband signalling
via MDIO.

We do not fully support running a USXGMII link with disabled
autonegotiation which leads to a non-working link between RTL93xx switch
and Aquantia PHYs running on USXGMII. To workaround this issue until
this support is added (if it is properly supported by the hardware),
force the Aquantia PHYs on affected devices to use inband signalling
instead of outband signalling. To achieve this, one can add

> managed = "in-band-status";

to the port definition in the DTS.

be used to reflect the port status. As no hardware port status
offloading is supported, blinking on traffic could result in increased
load due to the numerous LED updates.

5592faaa07 realtek: rtl839x: enable RTL8231 LED driver
To enable the use of the RTL8231 to control (port) LEDs, the driver
needs to be enabled in the build. Incorporate it into the kernel, so any
LED consumers also work in failsafe mode.

597e1fdf7f realtek: rtl839x: add port LED peripheral disable
Add a pinctrl-single node to the switch GPIO/LED control register that
disables the port LED peripheral when selected. When an RTL8231 is
instantiated, this is required to prevent the user config from being
overwritten by the peripheral.

As this is technically not a pin mux operation, but rather a peripheral
disable, using pinctrl-single for this purpose is bit of a hack, but it
does the job.

2fffb27c98 realtek: disable synchronous operation on RTL8231
It may be possible that the bootloader has left an RTL8231 expander
configured for synchronous operation, which requires the user to signal
that the new GPIO/LED states should be latched.

As drivers typically perform one operation at a time for the higher
level kernel framework, this would require a latch on every update,
which is not very useful. Disable synchronous operation to keeps things
simple.

c98289b074 realtek: fix regmap_field getter const qualifier
The allocated regmap_field object is not stored as a const reference, so
the helper function allocating the object should not return it as such.

Drop 'const' so the build doesn't complain about discarding the

75a33df5f6 realtek: fix RTL8231 LED toggle interval clamping
The loop scanning the available toggle rates would stop when the
requested interval exceeded the tested interval. Since the intervals are
searched from small to large, this would always trigger on the shortest
interval, or skip to the largest interval for small requested values.

To correctly clamp (ceil) the toggle rate, the loop needs to continue
until the condition is met, instead of breaking the loop.

4439b2ddc2 realtek: add support for D-Link DGS-1250-28X
Hardware specification
----------------------

* RTL9301 SoC, 1 MIPS 34KEc core @ 800MHz
* 512MB DRAM
* 64MB NAND Flash
* 24 x 10/100/1000BASE-T ports
* 4 x 10G SFP+ ports
* Power LED, Console LED, Fan Fault LED
* Reset button on front panel
* LM75 temperature sensor
* Atmel AT24C02 2kb eeprom
* fan (controllable via gpio for on/off and LM75 for low/high speed)
* UART (115200 8N1) via RJ45

Installation using serial interface
-----------------------------------

 1. Prepare TFTP server & connect to serial port.
 2. Connect DGS-1250 to your computer or network with one of the
    1G ports. All of them will be fine.
 3. Power on DGS-1250 and interrupt autoboot with "&".
 4. Change U-Boot startup sequence
	> setenv silent
	> setenv bootcmd 'cp.l 0xb4200000 0x84000000 0x300000; bootm 0x84000000'
	> saveenv
 5. Enable networking within U-Boot.
	> rtk network on
 6. Set switch IP and TFTP server IP (optional, adjust to your setup).
	> setenv ipaddr <ip>
	> setenv serverip <ip>
 7. Download initramfs image from TFTP server.
	> tftpboot 0x84000000 <image name>
 8. Boot with the downloaded image.
	> bootm 0x84000000
 9. With rambooted OpenWrt, backup the stock firmware.
    THIS IS CRITICAL! /dev/mtd3 contains data that is not provided
    in the downloadable vendor firmware images.
10. Copy sysupgrade image to the device.
11. Perform sysupgrade with the sysupgrade image.
12. After reboot, you should have functional OpenWrt.

Installation using OEM webinterface
-----------------------------------

This is not possible because the vendor image uses a ubifs based
loading technique with encrypted images. To be precise the boot
sequence basically runs as follows.

 1. U-Boot starts
 2. U-Boot mounts 62MB ubifs from mtd3
 3. U-Boot reads Linux kernel from file uImage inside ubifs
 4. Linux starts (this is a initramfs image)
 5. Linux mounts ubifs
 6. Linux calls a loader binary
 7. Depending on current configuration first (file Image1) or
    second firmware image (file Image2) is loaded and decrypted
 8. Inside the decrpyted firmware image there is a executable
    named “switch”
 9. "switch" executable is run and the switch comes alive

Reverting to stock firmware
---------------------------

 1. Boot OpenWrt from initramfs (like in installation section above)
 2. Restore partition /dev/mtd3 from backup
 3. Erase Openwrt special U-Boot env
	# mtd erase mtd1
 4. reboot

ae2ce7faa3 realtek: mdio-serdes: rename debug serdes pages
The initial page naming of the debugfs page registers in the mdio
serdes driver was a mix of RTL839x and RTL93xx. Developing the
Realtek pcs driver, it was discovered that the RTL93xx IP block
shares a lot of the registers with the RTL8295 PHY.

The RTL839x serdes development is quite okay and currently on hold.
Thus drop the RTL839x derived page names and substitute them for
their RTL93xx counterpart.

This is only a cosmetic change for better readability.

They can ship packets via DMA without further offloading features.
Even on the RTL931x devices they can barely reach 50MB/s. In the

better reflect the performance set the link speed to 1000.

Add patches that extends the upstream smbus support in sfp driver. This
