Hi,

Series adds watchdog support for Renesas RZ/G3S (R9A08G045) SoC.

Patches do the following:
- patch 1/11 selects CONFIG_PM for the watchdog driver
- patch 2/11 adds clock and reset support for watchdog
- patches 3-7/11 adds fixes and cleanup for the watchdog driver
- patch 8/11 adds suspend to RAM to the watchdog driver (to be used by
  RZ/G3S)
- patch 9/11 documents the RZ/G3S support
- patches 10-11/11 add device tree support

It is expected that the clock and device tree support will go through
Geert's tree while the rest of the patches through the watchdog tree.

Thank you,
Claudiu Beznea

Changes in v2:
- added patch "watchdog: rzg2l_wdt: Select PM"
- propagate the return status of rzg2l_wdt_start() to it's callers
  in patch "watchdog: rzg2l_wdt: Use pm_runtime_resume_and_get()" 
- propagate the return status of rzg2l_wdt_stop() to it's callers
  in patch "watchdog: rzg2l_wdt: Check return status of pm_runtime_put()" 
- removed pm_ptr() from patch "watchdog: rzg2l_wdt: Add suspend/resume support"
- s/G2UL/G2L in patch "dt-bindings: watchdog: renesas,wdt: Document RZ/G3S support"
- collected tags
