Subject: [PATCH v4 0/5] Allwinner H6 watchdog support
Date: Tue, 21 May 2019 18:03:25 +0200
Message-ID: <20190521160330.28402-1-peron.clem@gmail.com> (raw)

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

Changes since v3:
 - Remove A64 compatible
 - Introduce specific bindings for r-wdt

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

Changes since v1:
 - Use A64 compatible instead of H6
 - Remove dt-bindings patch
 - Change watchdog status to disabled
 - Add r_watchdog node patch
 - Add enable sunxi watchdog patch
