[PATCH v2 0/3] arm64: Realtek RTD1295 watchdog

[PATCH v2 0/3] arm64: Realtek RTD1295 watchdog

[Andreas Färber]

Hello,

This series adds the watchdog for the Realtek RTD1295 SoC.

v2 does minor cleanups.

The implementation is based on register offsets seen in the vendor DT,
as well as older mach-rtk119x code published by QNAP.

The DT node depends on my RTD1295 clk series.

More experimental patches at:
https://github.com/afaerber/linux/commits/rtd1295-next

Have a lot of fun!

Cheers,
Andreas

v1 -> v2:
* Prepared remove (Guenther)
* Set timeout field (Guenther)
* Cleanups (Guenther, Andreas)

+- reg        :  Specifies the physical base address and size of registers
