A SerDes can host multiple PCS links: QSGMII binds four ports to one
SerDes, USXGMII variants up to eight. Today pcs-handle references the
SerDes as a whole, with no way to express which link inside the SerDes
a port wants. The driver gets away with this because it carries its own
port->link bookkeeping and the link slot is implicit in DSA's port
iteration order -- functional, but the wiring information lives nowhere
in DT.
The upcoming fwnode_pcs migration moves PCS lookup to the generic
fwnode provider API, which disambiguates multiple instances per fwnode
via phandle cells. To make that landable as small, code-only commits,
the DT needs to carry the link index ahead of time.
Bump #pcs-cells from 0 to 1 on every SerDes node in the four SoC DTSIs
and append the link cell to every pcs-handle reference across boards
and the SWITCH_PORT_* macros. Cell values match the existing wiring:
0 for single-link SerDes (10GBase-R, SGMII, fiber, single-link
USXGMII), 0..3 per SerDes for QSGMII and USXGMII-QX, 0..7 for the
RTL9311 octal USXGMII layout.
No code reads the new cell yet -- of_parse_phandle_with_args() in the
PCS driver already cooperates with cells = 0 or 1, and the DSA glue
uses of_parse_phandle() which ignores cells entirely. The change is
runtime-neutral on its own; it exists so the follow-up code patches
can be a few lines each instead of dragging a bridge counter into the
driver to invent slot numbers DT could have provided directly.

The nRESET pins of the RTL8224 PHYs on the PSX8/PSX10 are wired to GPIO6
(lan1-4) + GPIO10 (lan5-8) of the SoC, but this was never described in the
devicetree.
GPIO 6 is the global reset shared by (logical) PHYs 0-3 on MDIO bus0. GPIO
10 is the global reset shared by (logical) PHYs 8-11 on mdio bus0. It is
intentionally not declared as reset-gpios on any bus: the MDIO driver /
phylink only support a single reset GPIO per bus, not two (or more). And a
GPIO can only be used as reset-gpio on a single PHY. Attaching it to a
single PHY would still reset the other PHYs on the same chip as a side
effect, leaving their software state out of sync with the hardware and
likely breaking them.

A phy node in the dts has two properties:
- reg: the (overall) address of the phy
- realtek,smi-address: the address of the phy on its bus
This notation does not align with upstream. reg should be the address
of the phy on its bus. But where to get the overall address that is
needed for register writes to the hardware?
Luckily the mdio driver and the hardware design sync the ports and
phys (overall) addresses. Thus derive missing data from the dts port
nodes (below ethernet-ports). To realize this
- carve out the port mapping into a separate function to align with
the upstream driver.
- do more sanity checks and catch more inconsistencies
- raise more/better errors via dev_err_probe()
With this commit all dts files must be rewritten as follows:
- if phy has no realtek,smi-address leave it as is
- if phy has realtek,smi-address, write that value into the reg
property and drop realtek,smi-address.
Remark: This commit might bring some confusion about the phyXX and
phy@YY and <reg=YY> naming convention. To be somehow consistent with
the current port/phy identifiers from now on the dts will have:
- phyXX: where XX matches the port number
- phy@YY: where YY is the phy address on the mdio bus
- <reg=YY>: where YY is the phy address on the mdio bus

In most drivers upstream use "ethernet-ports" instead of "ports"
in dts. Especially the upstream rtl9300 mdio driver uses this to
lookup the port/phy mapping. Do the same downstream. There is no
need to adapt the dsa driver because it scans the dts via
for_each_node_by_name(dn, "port").

The dts for RTL93xx devices has duplicate data about the
smi bus of a phy node. The parent node declares the number
of the bus and the realtek,smi-address attribute does the
same.
Remove the bus part from the realtek,smi-address attribute
and lookup the bus from the parent node. While we are here
remove all realtek,smi-address attributes where phy id
matches the bus address. The driver will use that as a
fallback.

The rtl9300,smi-address property was first developed for the RTL930x
targets. So it got a device specific prefix. Nowadays it is used for
RTL931x targets too. Convert it to our gerneric realtek prefix.

The mdio controller got its own dts node with a dedicated bus node.
Until now it still searches the phy nodes in the ethernet node.
Change the driver so it searches the nodes at the right location.
For this to work move the phy nodes in all dts/dtsi over to the new
bus node. Use the following replacement rule:
Replace old full declaration
ðernet0 {
mdio-bus {
...
};
};
and old abbreviated declaration
&mdio {
...
};
simply with the new declaration
&mdio_bus0 {
...
};

The Plasma Cloud PSX8 Switch is a 8 port multi-GBit switch with
8x 10/100/1000/2500BaseT Ethernet ports.
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
- 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
* The image must be copied using scp to /tmp of the device
scp openwrt-realtek-rtl930x-plasmacloud_psx8-squashfs-sysupgrade.bin root@[IP address of the device]:/tmp/
* start sysupgrade without saving the original vendor configuration
sysupgrade -n /tmp/openwrt-realtek-rtl930x-plasmacloud_psx8-squashfs-sysupgrade.bin
Installation via u-boot
-----------------------
If you have an TFTP server connected to the switch, it is possible to
directly install the device using the factory image from u-boot
# setup networking and IP of TFP server
rtk network on
setenv ipaddr 10.100.100.99
setenv serverip 10.100.100.20
# get factory image
tftp 0x84000000 factory.bin
# erase firmware partitions
sf probe 0
sf erase 0x100000 0x01f00000
# write firmware to both partitions
sf write ${fileaddr} 0x100000 ${filesize}
sf write ${fileaddr} 0x1080000 ${filesize}
# adjust the boot commands
setenv bootargs "mtdparts=spi0.0:896k(u-boot),64k(u-boot-env),64k(u-boot-env2),15872k(inactive),15872k(firmware2)"
setenv bootcmd "rtk init; bootm 0xb5080000"
# restart
reset
Debug
-----
* Connect serial as per the layout above. Connection parameters: 115200 8N1.
* A tftp server is required, 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 of device:
setenv ipaddr 192.168.1.6
* Download initramfs from TFTP server:
tftpboot 0x84000000 192.168.1.111:openwrt-realtek-rtl930x-plasmacloud_psx8-initramfs-kernel.bin
* Boot loaded file:
bootm 0x84000000
