Subject: [PATCH 0/2] Reset related fixes for rzg2l_wdt

Dear All,

this series addresses a couple of issues found with the rzg2l_wdt
driver:
1) on the RZ/Five SoC it was observed that changing the timeout
   wouldn't reset the system as expected
2) on the RZ/V2M SoC it was observed that calling into the restart
   callback from the reboot command wouldn't reboot the system
   straight away

As it turns out, the RZ/Five watchdog IP requires the module clock
to be supplied during a reset.
On RZ/V2M, a specific procedure has to be followed to reset the
watchdog IP.

This series comes with two patches, one to fix the problem affecting
RZ/Five, and one to fix the problem affecting RZ/V2M.

Thanks,
Fab
