3f4d6da453 realtek: Enable gpio-restart driver
Add the gpio-restart driver to the realtek build. This way devices,
which cannot reliably perform resets using the SoC's internal reset
logic, can use a GPIO line to drive the SoC's hard reset input.

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.

cda0460ad3 realtek: add legacy realtek GPIO driver for rtl9300 support
The otto GPIO driver does not work with rtl9300 SoCs. Add
the legacy driver again and use that by default in the 9300 .dtsi

9bac1c20b8 realtek: backport gpio-realtek-otto driver from 5.13 to 5.10
This patch backports "gpio-realtek-otto" driver to Kernel 5.10.
"MACH_REALTEK_RTL" is used as a platform name in upstream, but "RTL838X"
is used in OpenWrt, so update the dependency by the additional patch.

Note: GPIO mapping is changed in the upstreamed driver.

fbd675c668 realtek: drop rtl838x gpio driver from 5.10
To backport the upstreamed driver (gpio-realtek-otto) from 5.13, drop the
old driver from realtek target.

And, modify 301-gpio-add-rtl838x-driver.patch to remove rtl838x GPIO
support and rename it only for rtl8231 GPIO support.
