Subject: [PATCH v2 0/4] Add CPG/MSSR support for RZ/N2H SoC

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This series adds support for the Clock Generator, Module Standby, and
Software Reset (CPG/MSSR) found on the Renesas RZ/N2H (R9A09G087) SoC.
The implementation reuses the existing RZ/T2H (R9A09G077) CPG/MSSR
driver, as both SoCs share the same clock and reset architecture.

Note, Ive split the CPG/MMSR support into separate series previously
the patches were part of series [1].

v1->v2:
- Rebased on latest linux-next.
- Update commit messages for patches 1/4 and 4/4
- Patches 2/4 and 3/4 are new patches to add PCLKL core clock
- Added reviewed-by tags.

Cheers,
Prabhakar
