fae3ac3560 realtek: build sane factory images for DGS-1210 models
During upload of firmware images the WebUI and CLI patch process
extracts a version information from the uploaded file and stores it
onto the jffs2 partition. To be precise it is written into the
flash.txt or flash2.txt files depending on the selected target image.
This data is not used anywhere else. The current OpenWrt factory
image misses this label. Therefore version information shows only
garbage. Fix this.

Before:
DGS-1210-20> show firmware information

36acb3db03 realtek: EnGenius EWS2910P: declare and hog the poe-enable GPIO
GPIO 1 on the RTL8231 is used to force the PoE MCU to disable power
outputs. It is not used by any driver, but if accidentally set low,
PoE outputs are disabled. This situation is hard to debug, and
requires knowledge of the Broadcom PoE protocol used by the MCU.

To prevent this situation, hog it as an output high. This is
consistent with the ZyXel GS1900 series handles it.

1005dc0a64 realtek: add DGS-1210-28 factory image
DGS-1210 switches support dual image, with each image composed of a
kernel and a rootfs partition. For image1, kernel and rootfs are in
sequence. The current OpenWrt image (written using a serial console),
uses those partitions together as the firmware partition, ignoring the
partition division. The current OEM u-boot fails to validate image1 but
it will only trigger firmware recovery if both image1 and image2 fail,
and it does not switch the boot image in case one of them fails the
check.

The OEM factory image is composed of concatenated blocks of data, each
one prefixed with a 0x40-byte cameo header. A normal OEM firmware will
have two of these blocks (kernel, rootfs). The OEM firmware only checks
the header before writing unconditionally the data (except the header)
to the correspoding partition.

The OpenWrt factory image mimics the OEM image by cutting the
kernel+rootfs firmware at the exact size of the OEM kernel partition
and packing it as "the kernel partition" and the rest of the kernel and
the rootfs as "the rootfs partition". It will only work if written to
image1 because image2 has a sysinfo partition between kernel2 and
rootfs2, cutting the kernel code in the middle.

Steps to install:

1) switch to image2 (containing an OEM image), using web or these CLI
   commands:
   - config firmware image_id 2 boot_up
   - reboot
2) flash the factory_image1.bin to image1. OEM web (v6.30.016)
   is crashing for any upload (ssh keys, firmware), even applying OEM
   firmwares. These CLI commands can upload a new firmware to the other
   image location (not used to boot):
   - download firmware_fromTFTP <tftpserver> factory_image1.bin
   - config firmware image_id 1 boot_up
   - reboot

To debrick the device, you'll need serial access. If you want to
recover to an OpenWrt, you can replay the serial installation
instructions. For returning to the original firmware, press ESC during
the boot to trigger the emergency firmware recovery procedure. After
that, use D-Link Network Assistant v2.0.2.4 to flash a new firmware.

The device documentation does describe that holding RESET for 12s
trigger the firmware recovery. However, the latest shipped U-Boot
"2011.12.(2.1.5.67086)-Candidate1" from "Aug 24 2021 - 17:33:09" cannot
trigger that from a cold boot. In fact, any U-Boot procedure that relies
on the RESET button, like reset settings, will only work if started from
a running original firmware. That, in practice, cancels the benefit of
having two images and a firmware recovery procedure (if you are not
consider dual-booting OpenWrt).

4d1fc8916c realtek: EnGenius EWS2910P: add support for SFP ports
The SFP cages 9F and 10F share the same SCL line. Currently, there
isn't a good way to model this. Thus, only one SFP port can be fully
supported.

Cage 10F is fully supported with an I2C bus and sfp handle. Linux
automatically handles enabling or disabling the TX laser.

Cage 9F is only parially supported, without the sfp handle. The SDA
line is hogged as an input, so that it remains high. SCL transitions
sould not affect modules connected to this cage. The default value of
the tx-disable line is high (active). It is exported as a gpio, but
the laser is off by default. To enable the laser:

    echo 0 > /sys/class/gpio/sff-p9-tx-disable/value

Thus, both modules can be used for networking, but only 10F will be
able to detect and identify a plugged in SFP module.

2cfaab4549 realtek: add support for EnGenius EWS2910P
Add support for the Engenius EWS2910P PoE switch. This is an RTL8380
based switch with two SFP slots, and PoE 802.3af one every RJ-45 port.

The specs say 802.3af, but the vendor firmware configures the PSE for
a budget of 31W, indicating 802.3at support.

Specifications:
---------------
* SoC:       Realtek RTL8380M
* Flash:     32 MiB SPI flash Macronix MX25L25635E
* RAM:       256 MiB (As reported by bootloader)
* Ethernet:  16x 10/100/1000 Mbps with PoE
              2x SFP slots
* Buttons:   1 "Reset" button on front panel
             1 "LED mode: button on front panel
             1 "On/Off" Toggle switch on the back
* Power:     48V-54V DC barrel jack
* UART:      1 serial header (JP1) with populated 2.54mm pitch header
             Labeled GRTV for ground, rx, tx, and 3.3V respectively
* PoE:       1 STM ST32F100 microcontroller
             2 BCM59111 PSE chips
Works:
------
  - (8) RJ-45 ethernet ports
  - Switch functions
  - LEDs and buttons

Not yet enabled:
----------------
  - SFP ports (will be enabled in a subsequent change)
  - Power-over-Ethernet (requires realtek-poe package)

Install via web interface:
-------------------------

The factory firmware will accept and flash the initramfs image. It is
recommended to flash to "Partition 0". Flashing to "Partition 1" is
not supported at this point.

The factory web GUI will show the following warning:

 " Warning: The firmware version is v0.00.00-c0.0.00
     The firmware image you are uploading is older than the current
     firmware of the switch. The device will reset back to default
     settings. Are you sure you want to proceed?"

This is expected when flashing OpenWrt. After the initramfs image
boots, flash the -sysupgrade using either the commandline or LuCI.

Install via serial console/tftp:
--------------------------------

The u-boot firmware will not stop the boot, regardless of which key is
pressed. To access the u-boot console, ground out the CLK (pin 16) of
the ROM (U22) when u-boot is reading the linux image. If timed
correctly, the image CRC will fail, and u-boot will drop to a shell:
    > rtk network on
    > setenv ipaddr <address of tftp server>
    > tftp $(freemem) <name-of-initramfs-image.bin>
    > bootm

Then flash the -sysupgrade using either the commandline or luci.

adbdfc9366 realtek: add support for power LED on Netgear GS108Tv3
The Netgear GS108Tv3 is already supported by OpenWrt, but is missing LED
support. After OpenWrt installation, all LEDs are off which makes the
installation quite confusing.
This enables support for the green/amber power LED to give feedback
about the current status.

This is basically just a verbatim copy of commit c4927747d2 ("realtek:
add support for power LED on Netgear GS308Tv1").

Please note that both LEDs are wired up in an anti-parallel fashion,
which means that only one of both LEDs/colors can be switched on at the
same time. If both LEDs/colors are switched on simultanously, the LED
goes dark.

             + PIn 4 - GND

Serial connection parameters:  115200 8N1.

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

OEM upgrade method:

* Log in to OEM management web interface
* Navigate to Maintenance > Firmware
* Select the HTTP radio button
* Select the Active radio button
* Use the browse button to locate the
realtek-rtl838x-zyxel_gs1900-24e-initramfs-kernel.bin
file and select open so File Path is updated with filename.
* Select the Apply button. Screen will display "Prepare
for firmware upgrade ...".
*Wait until screen shows "Do you really want to reboot?"
then select the OK button
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
   > sysupgrade -n /tmp/realtek-rtl838x-zyxel_gs1900-24e-squashfs-sysupgrade.bin
   it may be necessary to restart the network (/etc/init.d/network restart) on
   the running initramfs image.

U-Boot TFTP method:

* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
* Set up a TFTP server on your client and make it serve the initramfs image.
* Connect serial, power up the switch, interrupt U-boot by hitting the
  space bar, and enable the network:
   > rtk network on
* Since the GS1900-24E is a dual-partition device, you want to keep the OEM
  firmware on the backup partition for the time being. OpenWrt can only boot
  from the first partition anyway (hardcoded in the DTS). To make sure we are
  manipulating the first partition, issue the following commands:
  > setsys bootpartition 0
  > savesys
* Download the image onto the device and boot from it:
   > tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-rtl838x-zyxel_gs1900-24e-initramfs-kernel.bin
   > bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
   > sysupgrade -n /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24e-squashfs-sysupgrade.bin
   it may be necessary to restart the network (/etc/init.d/network restart) on
   the running initramfs image.

bde6311569 realtek: don't unmask non-maskable GPIO IRQs
On uniprocessor builds, for_each_cpu(cpu, mask) will assume 'mask'
always contains exactly one CPU, and ignore the actual mask contents.
This causes the loop to run, even when it shouldn't on an empty mask,
and tries to access an uninitialised pointer.

Fix this by wrapping the loop in a cpumask_empty() check, to ensure it
will not run on uniprocessor builds if the CPU mask is empty.

1Gbit ports, this is commonly a single XGMII link to an RTL8218D. There
is however no support for setting up the XGMII link on RTL9300/RTL9310,
thereby wiping the (RX/TX) setup done by u-boot and breaking the 1GBit
ports. No SerDes reset should be done for these links.

The handling of SGMII/HiSGMII, 1000BX or 10GR links is actually entirely
different. All these modes need to be suitably RX calibrated and the
pre- main and post- amplifiers set up properly for TX.

The 10GBit SFP+ fiber links are recalibrated instead of reset, which
e.g. is necessary when someone pulls a module out and puts another in.
This makes swapping out 10GBit fiber modules possible. 1GBit modules are
not yet supported, nor any modules with an internal phy.

             the right back of the PCB.
             Pinout (front to back):
             + Pin 1 - VCC marked with white dot
             + Pin 2 - RX
             + Pin 3 - TX
             + PIn 4 - GND

Serial connection parameters:  115200 8N1.

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

OEM upgrade method:

* Log in to OEM management web interface
* Navigate to Maintenance > Firmware
* Select the HTTP radio button
* Select the Active radio button
* Use the browse button to locate the
realtek-generic-zyxel_gs1900-16-initramfs-kernel.bin
file amd select open so File Path is update with filename.
* Select the Apply button. Screen will display "Prepare
for firmware upgrade ...".
*Wait until screen shows "Do you really want to reboot?"
then select the OK button
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
   > sysupgrade -n /tmp/realtek-generic-zyxel_gs1900-16-squashfs-sysupgrade.bin
   it may be necessary to restart the network (/etc/init.d/network restart) on
   the running initramfs image.

U-Boot TFTP method:

* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
* Set up a TFTP server on your client and make it serve the initramfs image.
* Connect serial, power up the switch, interrupt U-boot by hitting the
  space bar, and enable the network:
   > rtk network on
* Since the GS1900-16 is a dual-partition device, you want to keep the OEM
  firmware on the backup partition for the time being. OpenWrt can only boot
  from the first partition anyway (hardcoded in the DTS). To make sure we are
  manipulating the first partition, issue the following commands:
  > setsys bootpartition 0
  > savesys
* Download the image onto the device and boot from it:
   > tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-16-initramfs-kernel.bin
   > bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
   > sysupgrade -n /tmp/openwrt-realtek-generic-zyxel_gs1900-16-squashfs-sysupgrade.bin
   it may be necessary to restart the network (/etc/init.d/network restart) on
   the running initramfs image.

469030659c realtek: Use firewall4
The realtek target is not a router, but basic device, see DEVICE_TYPE.
The basic device type does not come with firewall by default, see
include/target.mk for details. The realtek target extended
DEFAULT_PACKAGES manually with firewall.

This changes the defaults to take firewall4 and nftables instead of
firewall and iptables. This also adds the additional package
kmod-nft-offload.

The only difference to the router type is the missing ppp,
ppp-mod-pppoe, dnsmasq and odhcpd-ipv6only package.

e83ab243be realtek: add support for Panasonic Switch-M8eG PN28080K
Panasonic Switch-M8eG PN28080K is a 8 + 1 port gigabit switch, based on
RTL8380M.

Specification:

- SoC		: Realtek RTL8380M
- RAM		: DDR3 128 MiB (Winbond W631GG8KB-15)
- Flash		: SPI-NOR 32 MiB (Macronix MX25L25635FMI-10G)
- Ethernet	: 10/100/1000 Mbps x8 + 1
  - port 1-8	: TP, RTL8218B (SoC)
  - port 9	: SFP, RTL8380M (SoC)
- LEDs/Keys	: 7x / 1x
- UART		: RS-232 port on the front panel (connector: RJ-45)
  - 3:TX, 4:GND, 5:GND, 6:RX (pin number: RJ-45)
  - 9600n8
- Power		: 100-240 VAC, 50/60 Hz, 0.5 A
  - Plug	: IEC 60320-C13
- Stock OS	: VxWorks based

Flash instruction using initramfs image:

1.  Prepare the TFTP server with the IP address 192.168.1.111
2.  Rename the OpenWrt initramfs image to "0101A8C0.img" and place it to
    the TFTP directory
3.  Download the official upgrading firmware (ex: pn28080k_v30000.rom)
    and place it to the TFTP directory
4.  Boot M8eG and interrupt the U-Boot with Ctrl + C keys
5.  Execute the following commands and boot with the OpenWrt initramfs
    image

    rtk network on
    tftpboot 0x81000000
    bootm

6.  Backup mtdblock files to the computer by scp or anything and reboot
7.  Interrupt the U-Boot and execute the following commands to re-create
    filesystem in the flash

    ffsmount c:/
    ffsfmt c:/

    this step takes a long time, about ~ 4 mins

8.  Execute the following commands to put the official images to the
    filesystem

    updatert <official image>

    example:

      updatert pn28080k_v30000.rom

    this step takes about ~ 40 secs

9.  Set the environment variables of the U-Boot by the following commands

    setenv loadaddr 0xb4e00000
    setenv bootcmd bootm
    saveenv

10: Download the OpenWrt initramfs image and boot with it

    tftpboot 0x81000000 0101A8C0.img
    bootm

11: On the initramfs image, download the sysupgrade image and perform
    sysupgrade with it

    sysupgrade <imagename>

12: Wait ~ 120 seconds to complete flashing

Note:

- "Switch-M8eG" is a model name, and "PN28080K" is a model number.
  Switch-M8eG has an another (old) model number ("PN28080"), it's not a
  Realtek based hardware.

- Switch-M8eG has a "POWER" LED (Green), but it's not connected to any
  GPIO pin.

- The U-Boot checks the runtime images in the flash when booting and
  fails to execute anything in "bootcmd" variable if the images are not
  exsisting.

- A filesystem is formed in the flash (0x100000-0x1DFFFFF) on the stock
  firmware and it includes the stock images, configuration files and
  checksum files. It's unknown format, can't be managed on the OpenWrt.
  To get the enough space for OpenWrt, move the filesystem to the head
  of "fs_reserved" partition by execution of "ffsfmt" and "updatert".

- On the other devices in the same series of Switch-M8eG PN28080K, the
  INT pin on the PCA9555 is not connected to anywhere.

Back to the stock firmware:

1. Delete "loadaddr" variable and set "bootcmd" to the original value

   on U-Boot:

     setenv loadaddr
     setenv bootcmd 'bootm 0x81000000'

   on OpenWrt:

     fw_setenv loadaddr
     fw_setenv bootcmd 'bootm 0x81000000'

2. Perform reset or reboot

  on U-Boot:

    reset

  on OpenWrt:

    reboot

7b19770525 realtek: add support for I-O DATA BSH-G24MB
I-O DATA BSH-G24MB is a 24 port gigabit switch, based on RTL8382M.

Specification:

- SoC		: Realtek RTL8382M
- RAM		: DDR2 128 MiB (Nanya NT5TU128M8HE-AC)
- Flash		: SPI-NOR 16 MiB (Macronix MX25L12835FM2I-10G)
- Ethernet	: 10/100/1000 Mbps x24
  - port 1-8	: RTL8218B
  - port 9-16	: RTL8218B (SoC)
  - port 17-24	: RTL8218B
- LEDs/Keys	: 2x, 1x
- UART		: pin header on PCB
  - JP2: 3.3V, TX, RX, GND from rear side
  - 115200n8
- Power		: 100 VAC, 50/60 Hz
  - Plug	: IEC 60320-C13

Flash instruction using sysupgrade image:

1. Boot BSH-G24MB normally
2. Connect BSH-G24MB to the DHCP enabled network
3. Find the device's IP address and open the WebUI and login
   Note: by default, the device obtains IP address from DHCP server of
         the network
4. Open firmware update page ("ファームウェア アップデート")
5. Rename the OpenWrt sysupgrade image to "bsh-g24mb_v100.image" and
   select it
6. Press apply ("適用") button to perform update
7. Wait ~150 seconds to complete flashing

Note:

- BSH-G24MB has a power-related LED ("電源"), but it's not connected to
  the GPIO of the SoC or RTL8231 and cannot be controlled. Instead of
  it, use system status LED on other than running-state.

- "sys_loop" LED indicates system status and loop-detection status in
  stock firmware.

- BSH-G24MB has 2x os-image partitions named as "RUNTIME"/"RUNTIME2" in
  16 MiB SPI-NOR flash and the size of image per partition is only
  6848 KiB. The secondary image is never used on stock firmware, so also
  use it on OpenWrt to get more space.

0890fb2df4 realtek: net: dsa: configure better brport flags when ports leave the bridge
Ensures that the DSA driver sets exactly the same default flags as the
bridge when a port joins or leaves.  Without this we end up with a
confusing flag mismatch, where DSA and bridge ports use different sets
of flags.

This is critical as the "learning" mismatch will be harmful to the
network, causing all traffic to be flooded on all ports.

The original commit was buggy, trying to set the flags one-by-one in a
loop.  This was not supported by the API and the end result was that
all but the last flag were cleared.  This bug was implicitly fixed
upstream by commit e18f4c18ab5b ("net: switchdev: pass flags and mask
to both {PRE_,}BRIDGE_FLAGS attributes").

This is a minimum temporary stop measure fix for the critical lack of
"learning" only.  The major API change associated with a full v5.12+
backport is neither required nor wanted. A simpler fix, moving the
call to dsa_port_bridge_flags() out of the loop,  has therefore been
merged into this modified backport.

9db651f4a2 realtek: use DT provided address for timers
The I/O base address for the timers was hardcoded into the driver,
or derived from the HW IRQ number as an even more horrible hack. All
supported SoC families have these timers, but with hardcoded addresses
the code cannot be reused right now.

71810eb068 realtek: clean up RTL930x timer DT node
The Realtek timer node for RTL930x doesn't have any child nodes, making
the use of '#address-cells' quite pointless. It is also not an interrupt
controller, meaning it makes no sense to define '#interrupt-cells'.

The I/O address for this node is also wrong, but this is hidden by the
fact that the driver associated with this node bypasses the usual DT
machinery and does it's own thing. Correct the address to have a sane
value, even though it isn't actually used.

a39fbaf23a realtek: use higher priority for timer interrupts
The assigned output index for the event timers was quite low, lower even
than the ethernet interrupt. This means that high network load could
preempt timer interrupts, possibly leading to all sorts of strange
behaviour.

Increase the interrupt output index of the event timers to 5, which is
the highest priority output and corresponds to the (otherwise unused)
MIPS CPU timer interrupt.

4b31717fb0 realtek: move RTL8231 definitions to board files
The RTL8231 is an external chip, and not part of the SoC. That means
it is more appropriate to define it in the board specific (base) files,
instead of the DT include for the SoC itself.

Moving the RTL8231 definition also ensures that boards with no GPIO
expander, or an alternative one, don't have a useless gpio1 node label
defined.

a93dfff10e realtek: add RTL8231 chip detection
When initialising the driver, check if the RTL8231 chip is actually
present at the specified address. If the READY_CODE value does not match
the expected value, return -ENXIO to fail probing.

This should help users to figure out which address an RTL8231 is
configured to use, if measuring pull-up/-down resistors is not an
option.

On an unsuccesful probe, the driver will log:

The SMI bus ID for RTL8231 currently defaults to 0, and can be
overridden from the devicetree. However, there is no value check on the
DT-provided value, aside from masking which would only cause value
wrap-around.

Change the driver to always require the "indirect-access-bus-id"
property, as there is no real reason to use 0 as default, and perform a
sanity check on the value when probing. This allows the other parts of
the driver to be simplified a bit.

5b8b382df9 realtek: Add support for ZxXEL XGS1250-12 Switch
The ZyXEL XGS1250-12 Switch is a 11 + 1 port multi-GBit switch with
8 x 1000BaseT, 3 x 1000/2500/5000/10000BaseT Ethernet ports and
1 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
 - Aquantia AQR113c 1/2.5/5/10 Gigabit PHYs
 - SFP+ 10GBit slot

Power is supplied via a 12V 2A 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, however the 10GBit SFP+ slot is not
supported.

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 /tmp/openwrt-realtek-rtl930x-zyxel_xgs1250-12-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.

Web recovery
------------
The XGS1250-12 has a handy web recovery that will load when U-boot does
not find a bootable kernel. In case you would like to trigger the web
recovery manually, partially overwrite the firmware partition with some
zeroes:

  # dd if=/dev/zero of=/dev/mtd5 bs=1M count=2

If you have serial connected you'll see U-boot will start the web recovery
and print it's listening on 192.168.1.1, but by default it seems to be on
the OEM default IP for the switch - 192.168.1.3. The web recovery only
listens on HTTP (80) and *not* on 443 (HTTPS) unlike the web UI.

Return to stock
---------------
You can flash the ZyXEL firmware images to return to stock:

  # sysupgrade -F -n XGS1250-12_Firmware_V1.00(ABWE.1)C0.bix

47f5a0a3ee realtek: Add support for ZyXEL GS1900-48 Switch
The GS1900-48 is a 48 + 2 port Gigabit L2 switch with 48 gigabit ports.
Hardware:
    RTL8393M SoC
    Macronix MX25l12805D (16MB flash)
    128MB RAM
    6 * RTL8218B external PHY
    2 * RTL8231 GPIO extenders to control the port LEDs, system LED and
    Reset button

2 Uplink ports are SFP cages which support 1000 Base-X mini GBIC modules.

Power is supplied via a 230 volt mains connector.
The board has a hard reset switch SW1, which is is not reachable from the outside.
J4 provides a 12V RS232 serial connector which is connected through U8 to
the 3.3V UART of the RTL8393. Conversion is done by U8, a SIPEX 3232EC.
To connect to the UART, wires can be soldered to R603 (TX)  and R602 (RX).

Installation:
Install the squashfs image via Realtek's original Web-Interface.

45053b507c realtek: Add support for SFP EEPROM-access over SMBus
The EEPROMs on SFP modules are compatible both to I2C as well
as SMBus. However, the kernel so far only supports I2C
access. We add SMBus access routines, because the I2C driver
for the RTL9300 HW only supports that protocol. At the same
time we disable I2C access to PHYs on SFP modules as otherwise
detection of any SFP module would fail. This is not in any
way problematic at this point in time since the RTL93XX
platform so far does not support PHYs on SFP modules.

This multiplexer directly controls the two masters and their shared

9e7149f729 realtek: revert to "standard" management configuration
The default management interface should be easy to find for users
doing "blind" installations without console access.  There are
already multiple examples in the forum of advanced early adopters
having problems locating the management interface after installing
OpenWrt.

Requiring tagged VLAN configration to access the initial management
interface creates unnecessary hassle at best. Errors on the other
end are close to impossible to debug without console access, even
for advanced users.  Less advanced users might have problems with
the concept of VLAN tagging.

Limiting management access to a single arbitrary port among up to
52 possible LAN ports makes this even more difficult, for no
reason at all. Users might have reasons to use a different port
for management.  And they might even have difficulties using the
OpenWrt selected one. The port might be the wrong type for their
management link (e.g copper instead of fibre).  Or they might
depend on PoE power from a device which they can't reconfigure.

User expectations will be based on
- OpenWrt defaults for other devices
- stock firmware default for the device in question
- common default behaviour of similar devices

All 3 cases point to a static IP address accessible on the native
VLAN of any LAN port.  A switch does not have any WAN port.  All
ports are LAN ports.

This changes the default network configuration in line with these
expectations.

_machine_halt was already removed in commit f4b687d1f0 ("realtek: use
kernel defined halt"), but quietly reintroduced in commit 8faffa00cb
("realtek: add support for the RTL9300 timer"). Let's remove it again.

927570f0a3 realtek: Add and enable watchdog node
Add and enable the Realtek Otto WDT peripheral found on these SoCs.

Default all devices to use standard (cold) reboot and "soc" resets.

Devices that require the PLL value fixup before restarting, should pick
the "cpu" or "software" reset mode. These devices also need to provide a
custom reboot mode, by adding the reboot argument to the kernel command
line:

    WDT reset mode  | kernel reboot mode
    ----------------+---------------------------------------
    soc             | reboot=cold (default if not specified)
    cpu             | reboot=warm
    software        | reboot=software

Preferrably, these devices should use an alternative restart method like
gpio-restart to provide reliable restarts.

Note that watchdog restarts are not yet exposed, since the
_machine_restart override is still present.

no clock driver is currently available. Instead, use a fixed-clock to
provide the clock frequency, and update the dependent peripherals.

Lexra bus clock frequencies:
- RTL838x: 200MHz
- RTL839x: 200MHz

72ae8314f5 realtek: reset both ethernet NIC and queues
Recent versions of Realtek's SDK reset both the ethernet NIC and queues
(SW_NIC_RST and SW_Q_RST bits) when initialising the hardware.

Furthermore, when issuing a CPU reset on the Zyxel GS1900-8 (not
supported by any current driver), the networking part of the SoC is not
reset. This leads to unresponsive network after the restart. By
resetting both the ethernet NIC and queues, networking always comes up
reliably.

d990f805c0 realtek: re-enable IPv6 routing
Commit 03e1d93e07 ("realtek: add driver support for routing
offload") added routing offload for IPv4, but broke IPv6 routing
completely.  The routing table is empty and cannot be updated:

 root@gs1900-10hp:~# ip -6 route
 root@gs1900-10hp:~# ip -6 route add unreachable default
 RTNETLINK answers: Invalid argument

As a side effect, this breaks opkg on IPv4 only systems too,
since uclient-fetch fails when there are no IPv6 routes:

 root@gs1900-10hp:~# uclient-fetch http://192.168.99.1
 Downloading 'http://192.168.99.1'
 Failed to send request: Operation not permitted

Fix by returning NOTIFY_DONE when offloading is unsupported, falling
back to default behaviour.

9a4b8d6c30 realtek: fix compile errors in rtl838x_eth.c for 5.10
this patch fixes the following errors when compiling:

- "unsigned int txqueue" is added as an additional parameter of
  ndo_tx_timeout in net_device_ops (include/linux/netdevice.h)

- "mac_link_state" in phylink_mac_ops (include/linux/phylink.h)
  is renamed to "mac_pcs_get_state" and changed the return value
  to void from int

- several parameters are added to "mac_link_up" in phylink_mac_ops
  (include/linux/phylink.h) and the order of the parameters is
  changed

  added:
    - int speed
    - int duplex
    - bool tx_pause
    - bool rx_pause

- a parameter "phy_interface_t *interface" is added to of_get_phy_mode
  (drivers/of/of_net.c) and returns the state instead of phy mode

ddaeb73de0 realtek: update soc dtsi in 5.10 for backported drivers
this patch updates SoC dtsi (rtl838x.dtsi, rtl930x.dtsi) for the
following backported drivers:

- gpio-realtek-otto (5.13)
- spi-realtek-rtl (5.12)
- irq-realtek-rtl (5.12)

And, disable SoC GPIO node (gpio0) in rtl930x.dtsi in dts-5.10.
Currently, the upstreamed driver doesn't support the GPIO controller on
RTL930x SoC.

0de230bd0c realtek: copy dts directory for Kernel 5.10
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.

c5b44af2fc realtek: add ZyXEL GS1900-24HPv2 support
The ZyXEL GS1900-24HPv2 is a 24 port PoE switch with two SFP ports, similar to the other GS1900 switches.

Specifications
--------------
* Device:    ZyXEL GS1900-24HPv2
* SoC:       Realtek RTL8382M 500 MHz MIPS 4KEc
* Flash:     16 MiB
* RAM:       W631GG8MB-12 128 MiB DDR3 SDRAM
             (stock firmware is configured to use only 64 MiB)
* Ethernet:  24x 10/100/1000 Mbps, 2x SFP 100/1000 Mbps
* LEDs:      1 PWR LED (green, not configurable)
             1 SYS LED (green, configurable)
             24 ethernet port link/activity LEDs (green, SoC controlled)
             24 ethernet port PoE status LEDs
             2 SFP status/activity LEDs (green, SoC controlled)
* Buttons:   1 "RESTORE" button on front panel
             1 "RESET" button on front panel
* Power      120-240V AC C13
* UART:      1 serial header (J41) with populated standard pin connector on
             the left edge of the PCB, angled towards the side.
             The casing has a rectangular cutout on the side that provides
             external access to these pins.
             Pinout (front to back):
             + GND
             + TX
             + RX
             + VCC

Serial connection parameters for both devices: 115200 8N1.

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

OEM upgrade method:

(Possible on master once https://patchwork.ozlabs.org/project/openwrt/patch/20210624210408.19248-1-bjorn@mork.no/ is merged)

* Log in to OEM management web interface
* Navigate to Maintenance > Firmware > Management
* If "Active Image" has the first option selected, OpenWrt will need to be
  flashed to the "Active" partition. If the second option is selected,
  OpenWrt will need to be flashed to the "Backup" partition.
* Navigate to Maintenance > Firmware > Upload
* Upload the openwrt-realtek-generic-zyxel_gs1900-24hp-v2-initramfs-kernel.bin
  file by your preferred method to the previously determined partition.
  When prompted, select to boot from the newly flashed image, and reboot the switch.
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
   > sysupgrade -n /tmp/openwrt-realtek-generic-zyxel_gs1900-24hp-v2-squashfs-sysupgrade.bin
   it may be necessary to restart the network (/etc/init.d/network restart) on
   the running initramfs image.

U-Boot TFTP method:

* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
* Set up a TFTP server on your client and make it serve the initramfs image.
* Connect serial, power up the switch, interrupt U-boot by hitting the
  space bar, and enable the network:
   > rtk network on
* Since the GS1900-24HPv2 is a dual-partition device, you want to keep the OEM
  firmware on the backup partition for the time being. OpenWrt can only boot
  from the first partition anyway (hardcoded in the DTS). To make sure we are
  manipulating the first partition, issue the following commands:
  > setsys bootpartition 0
  > savesys
* Download the image onto the device and boot from it:
   > tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-24hp-v2-initramfs-kernel.bin
   > bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
   > sysupgrade -n /tmp/openwrt-realtek-generic-zyxel_gs1900-24hp-v2-squashfs-sysupgrade.bin
   it may be necessary to restart the network (/etc/init.d/network restart) on
   the running initramfs image.
