[v5,0/4] Allwinner H6 watchdog support

Message

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.

Thanks,
Clément

 - Delete specific bindings for r-wdt
