Hi,

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

Patches do the following:
- patch 1/9 makes the driver depend on ARCH_RZG2L || ARCH_R9A09G011
- patch 2/9 makes the driver depend on PM
- patches 3-7/9 adds fixes and cleanups for the watchdog driver
- patch 8/9 adds suspend to RAM to the watchdog driver (to be used by
  RZ/G3S)
- patch 9/9 documents the RZ/G3S support

Thank you,
Claudiu Beznea

Changes in v9:
- dropped patch "watchdog: rzg2l_wdt: Power on the PM domain in
  rzg2l_wdt_restart()" until further clarifications; this will not
  impact any behavior as the RZ/G3S power domain support is not
  instantiated
- on patch "watchdog: rzg2l_wdt: Remove reset de-assert from probe"
  call pm_runtime_put() in case the reset deassert fails

Changes in v8:
- added patch 9
- collected tags

Changes in v7:
- updated the dependency on patch 2/9

Changes in v6:
- update patch 2/9 description
- fixed the dependency on COMPILE_TEST previously introduced in patch
  2/9

Changes in v5:
- updated description of patch 2/9
- simplify the code in patch 2/9 by using on a new line:
  depends on PM || COMPILE_TEST

Changes in v4:
- added patch "watchdog: rzg2l_wdt: Restrict the driver to ARCH_RZG2L and
  ARCH_R9A09G011"
- collected tags

Changes in v3:
- make driver depend on PM not select it
- drop patches already accepted (patches 1, 10, 11 from v2)
- re-arranged the tags in patch 8/8 as they were messed by b4 am/shazam

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
