[PATCH v3 0/4] Allwinner H6 watchdog support

Hi,

Allwinner H6 SoC has two watchdogs.

As we are not sure that both A64 and H6 are stricly identical, I have
introduced the H6 bindings.

After investigation it seems that on some boards the first watchdog doesn't
make it properly reboot. Please see details in the commit log.

I think it's proper to add it with a comment anyway.

The r_watchdog is still available and usable on all the H6 boards.

Maybe it would be proper to introduce a "allwinner,sun50i-h6-r-wdt" bindings?

Thanks,
Clément

Changes since v2:
- Reintroduce H6 bindings
- Add watchdog Maintainters / ML
- Add Martin Ayotte test results

Changes since v1:
- Use A64 compatible instead of H6
