Hi Wim, Wolfram, Simon, Magnus,
This patch series add restart support for r8a7791/koelsch through the watchdog
in the DA9063 PMIC. Restart can be triggered in two ways:
1. Timeout of the watchdog timer,
2. Manual system restart, shutting down the DA9063.
Dependencies:
- There are no strict merge order dependencies,
- While manual restart depends on patch 1, patches 3 and 4 can be merged
now, as restart on watchdog timeout works without patch 1.
Patches:
- Patch 1 is intended for the watchdog tree (based on watchdog/next),
- Patch 2 is intended for the i2c tree (based on i2c/next),
- Patches 3 and 4 are intended for the shmobile tree (based on
renesas-devel-20141209-v3.18).
This was tested on r8a7791/koelsch.
I expect this restart method to be usable on r8a7791/lager and r8a7794/alt,
too.
Thanks!
