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)
