[v2,0/3] watchdog: pm8916_wdt: Some minor improvements

Message

Optimize the pm8916_wdt.c driver a bit by pinging the watchdog using a
write instead of read-modify-write. Also report the reboot reason to
userspace and (temporarily) ping the watchdog from the kernel if it was
already enabled by the bootloader.

Changes in v2: Improve error handling (suggested by Guenter)

  watchdog: pm8916_wdt: Avoid read of write-only PET register
