5f026f1272 realtek: rtl838x: label switch port dts nodes
Although PHY nodes are labeled, the port nodes were not. Labeling of
ports is useful for 'status = "disabled"' ports, which is supported
since commit 9a7f17e11f ("realtek: ignore disabled switch ports")

48f3746fe5 realtek: switch RTL838X/RTL839X DT to new clock driver
Use new DT clockdriver syntax for RTL838X/RTL839X targets. To make it work
we need to change some nodes:
- define the external oscillator speed (25MHz)
- define SRAM
- add clock controller
- Add second CPU for RTL839X
- map all devices to new clocks
- Remove dummy LXB clock
- add CPU OPP table

a63aeaecf1 realtek: remove support for HPE 1920 series
Support for HPE 1920 images depends on two non-existent tools (mkh3cimg
and mkh3cvfs) from the in the firmware-utils package. Revert commit
f2f09bc002 ("realtek: add support for HPE 1920 series") until support
for these tools is merged and made available in OpenWrt.

f2f09bc002 realtek: add support for HPE 1920 series
Hardware information:
---------------------

- HPE 1920-8G:
  - RTL8380 SoC
  - 8 Gigabit RJ45 ports (built-in RTL8218B)
  - 2 SFP ports (built-in SerDes)

- HPE 1920-16G / HPE 1920-24G (same board):
  - RTL8382 SoC
  - 16/24 Gigabit RJ45 ports (built-in RTL8218B, 1/2 external RTL8218D)
  - 4 SFP ports (external RTL8214FC)

- Common:
  - RJ45 RS232 port on front panel
  - 32 MiB NOR Flash
  - 128 MiB DDR3 DRAM
  - PT7A7514 watchdog

Booting initramfs image:
------------------------

- Prepare a FTP or TFTP server serving the OpenWrt initramfs image and
  connect the server to a switch port.

- Connect to the console port of the device and enter the extended
  boot menu by typing Ctrl+B when prompted.

- Choose the menu option "<3> Enter Ethernet SubMenu".

- Set network parameters via the option "<5> Modify Ethernet Parameter".
  Enter the FTP/TFTP filename as "Load File Name" ("Target File Name"
  can be left blank, it is not required for booting from RAM). Note that
  the configuration is saved on flash, so it only needs to be done once.

- Select "<1> Download Application Program To SDRAM And Run".

Initial installation:
---------------------

- Boot an initramfs image as described above, then use sysupgrade to
  install OpenWrt permanently. After initial installation, the
  bootloader needs to be configured to load the correct image file

- Enter the extended boot menu again and choose "<4> File Control",
  then select "<2> Set Application File type".

- Enter the number of the file "openwrt-kernel.bin" (should be 1), and
  use the option "<1> +Main" to select it as boot image.

- Choose "<0> Exit To Main Menu" and then "<1> Boot System".

NOTE: The bootloader on these devices can only boot from the VFS
filesystem which normally spans most of the flash. With OpenWrt, only
the first part of the firmware partition contains a valid filesystem,
the rest is used for rootfs. As the bootloader does not know about this,
you must not do any file operations in the bootloader, as this may
corrupt the OpenWrt installation (selecting the boot image is an
exception, as it only stores a flag in the bootloader data, but doesn't
write to the filesystem).

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.

Tested on a Netgear GS110TPPv1.

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.

d3a62bea08 realtek: Add Lexra bus clock
The CPU peripherals on RTL83xx/RTL930x are connected to the CPU via the
Lexra bus. This bus can provide a clock signal to these peripherals, but
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
- RTL930x: 175MHz

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.

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.
