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.

Since f1f0572d1 ("remove redundant integrated phy attribute") the
phy-is-integrated attribute of an phy in the dts is obsolete.
This was important for the INTERNAL_PHY() macro. Now it is
useless. Convert the macro to its successor 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.

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").

After having moved the configuration code and sequences from PHY and
DSA drivers to the PCS driver, add the hooks in PCS driver and remove
calls in PHY and DSA drivers to let PCS driver setup the SerDes
entirely on its own.
Also add pcs-handle to device tree definitions for most of the switch
ports because, due to the refactoring of the SerDes configuration, this
is needed now for all SerDes-attached ports.

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 {
...
};

This patch adds "dts-5.10" directory to use backported drivers.
There are several specification changes in the new drivers, so there
are some compatibility issues in using dts/dtsi files for 5.4.
The old DTS files are moved to "dts-5.4", so their corresponding
kernel version is obvious as well.

- Power : 100-240 VAC, 50/60 Hz, 0.21 A
- Plug : IEC 60320-C13
Flash instruction using initramfs image:
1. Boot AML2-17GP normally
2. Set the IP address of computer to the range of 192.168.1.0/24, other
than 192.168.1.248 and connect computer to "WAN/CONSOLE" port of
AML2-17GP
3. Access to "http://192.168.1.248" and open firmware setting page
-- UI Language: 日本語 --
"メンテナンス" -> "デュアルイメージ"
-- UI Language: ENGLISH --
"Maintenance" -> "Dual Image"
4. Check "イメージ情報 (en: "Images Information")" and set the first
image to active by choosing "アクティブイメージ" (en: "Active
Image") in the partition "0"
5. open firmware upgrade page
-- UI Language: 日本語 --
"メンテナンス" -> "アップグレードマネージャー"
-- UI Language: ENGLISH --
"Maintenance" -> "Upgrade Manager"
6. Set the properties as follows
-- UI Language: 日本語 --
"アップグレード方式" : "HTTP"
"アップグレードタイプ" : "イメージ"
"イメージ" : "アクティブ"
"ブラウズファイル" : (select the OpenWrt initramfs image)
-- UI Language: ENGLISH --
"Upgrade Method" : "HTTP"
"Upgrade Type" : "Image"
"Image" : "(Active)"
"Browse file" : (select the OpenWrt initramfs image)
7. Press "アップグレード" (en: "Upgrade") button and perform upgrade
8. Wait ~150 seconds to complete flashing
9. After the flashing, the following message is showed and press "OK"
button to reboot
-- UI Language: 日本語 --
"成功!! 今すぐリブートしますか?"
-- UI Language: ENGLISH --
"Success!! Do you want to reboot now?"
10. After the rebooting, reconnect the cable to other port (1-16) and
open the SSH connection, download the sysupgrade image to the device
and perform sysupgrade with it
11. Wait ~120 seconds to complete sysupgrade
Note:
- The uploaded image via WebUI will only be written with the length
embedded in the uImage header. If the sysupgrade image is specified,
only the kernel is flashed and lacks the rootfs, this causes a kernel
panic while booting and bootloops.
To avoid this issue, initramfs image is required for flashing on WebUI
of stock firmware.
- This device has 1x LED named as "POWER", but it's not connected to the
GPIO of SoC and cannot be controlled.
- port 17 is named as "WAN/CONSOLE". This port is for the upstream
connection and console access (telnet/WebUI) on stock firmware.
Back to stock firmware:
1. Set "bootpartition" variable in u-boot-env2 partition to "1" by
fw_setsys
fw_setsys bootpartition 1
2. Reboot AML2-17GP
