Subject: [PATCH v3 0/4] Allwinner H6 watchdog support
Date: Sat, 18 May 2019 17:23:51 +0200 [thread overview]
Message-ID: <20190518152355.11134-1-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.
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
- Remove dt-bindings patch
- Change watchdog status to disabled
- Add r_watchdog node patch
- Add enable sunxi watchdog patch
