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.

Install via UART:
  1. Download the initramfs image, rename it to
     initramfs.itb, host it with the tftp server.
  2. Interrupt U-Boot and run these commands:
     tftpboot initramfs.itb
     bootm
  3. After openwrt boots up, use scp or luci web
     to upload sysupgrade.bin to upgrade.
Install via Uboot WebUI:
   - Only work when you flash a custom uboot with webui
   - Push the reset button for 5 seconds, then use broswer to
     access http://192.168.1.1/, then upload factory.bin.

The Zyxel XGS1x10 DTS overzealously tries to avoid redundancies. For
this the phy24/phy25 definitions were split into a common and a device
specific part. Understanding how these phys are defined is therefore
a little bit tricky. Add a little bit of redundancy to make the
definitions easier to read and understand in a single location.

The switch node is currently located outside of the switchcore@1b000000
tree. This makes it hard to find when referencing from other nodes in
this tree. Make it a subnode of switchcore and "retype" it to
ethernet-switch like upstream does.

This is not perfectly aligned as upstream just mixes the switchcore and
the ethernet-switch node into one. But this will be future work for
downstream.

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

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.

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
qualifier.

Fixes: 6ef6014 ("realtek: Add pinctrl support for RTL8231")
Signed-off-by: Sander Vanheule <sander@svanheule.net>
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.

Signed-off-by: Sander Vanheule <sander@svanheule.net>
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.

Signed-off-by: Sander Vanheule <sander@svanheule.net>
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.

Signed-off-by: Sander Vanheule <sander@svanheule.net>
Add the RTL8231 controlling the port LEDs to the devicetree, so users
can enable them. Using the appropriate link name, the netdev trigger can
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.

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.

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.

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.

The board is exactly identical to the ASUS RT-AX52, I've literally not changed a single thing.
Only AX52 is AX1800, PRO is AX3000.

SOC: MediaTek MT7981b
RAM: 256MB DDR3
FLASH: 128MB SPI-NAND (Winbond W25N01GV)
WIFI: Mediatek MT7981b DBDC 802.11ax 2.4/5 GHz
ETH: MediaTek MT7531 Switch
UART: 3V3 115200 8N1 (Pinout silkscreened / Do not ocnnect VCC)

Use the compiled asus_rt-ax52-pro-initramfs.trx file from the this repo.

Connect the PC via LAN to one of the yellow router ports and wait until your PC to get a DHCP lease.

Browse to http://192.168.50.1 or http://www.asusrouter.com/

If your router is brand new, finish the setup process and log into the Web-UI.

Navigate to Administration → Firmware Upgrade or use this link http://www.asusrouter.com/Advanced_FirmwareUpgrade_Content.asp.

Upload the .trx file to router

Wait for it to reboot

trx image is initramfs version. You must upgrade to squashfs version.

Browse to http://192.168.1.1/cgi-bin/luci/admin/system/flash

Upload asus_rt-ax52-pro-squashfs-sysupgrade.bin and use sysupgrade -n

Wait for it to reboot

SSH to 192.168.1.1 and set a root password, or browse to http://192.168.1.1

-------Revert to stock asus firmware ---------:
1: Download the rt-ax52 firmware from ASUS official website. Save the firmware to tftp server directory and rename to RT-AX52.trx

2: Connect the PC with TFTP server to the RT-AX52. Set a static ip on the ethernet interface of your PC. (ip address: 192.168.1.70, subnet mask:255.255.255.0)

3: Conect to the serial console, power on again, interrupt the autoboot process by pressing '4' when prompted. $ ubi remove linux
$ ubi remove jffs2
$ ubi remove rootfs
$ ubi remove rootfs_data
$ ubi create linux 0x45fe000
$ reset
then the dut will reboot,interrupt the autoboot process by pressing '2' when prompted. 2: Load System code then write to Flash via TFTP.
Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N) $: enter y
you will see the follow, type enter directly:
Input device IP (192.168.1.1) ==:
Input server IP (192.168.1.70) ==:

…_ENABLED()

We patch DMA_BUF to make it tristate, so once ALL_KMODS is selected it will
be built as a module even if previously disabled in the config.

So, since IO_URING_ZCRX does not depend on DMA_BUF linking will fail with:
aarch64-openwrt-linux-musl-ld: Unexpected GOT/PLT entries detected!
aarch64-openwrt-linux-musl-ld: Unexpected run-time procedure linkages detected!

make[6]: *** [scripts/Makefile.vmlinux:72: vmlinux.unstripped] Error 1

So, lets use IS_REACHABLE() to check for CONFIG_DMA_SHARED_BUFFER instead
to avoid adding a dependency to CONFIG_DMA_SHARED_BUFFER.
