[PATCH v2 0/5] pinctrl: renesas: rzg2l: Fix PM register caching

[Prabhakar]

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

Hi all,

This patch series addresses several issues with the PM register caching
implementation in the Renesas RZ/G2L pinctrl driver. The changes include:
- Fixing SMT register caching to account for the split SMT registers on
  RZ/V2H(P).
- Adding caching for the SR (Slew Rate) registers during PM suspend/resume.
- Handling the IOLH configuration for RZ/V2H(P) in the PM cache setup.
- Adding caching for the NOD (N-ch Open Drain) registers during PM
  suspend/resume.
- Ensuring that PUPD registers for dedicated pins on RZ/V2H(P) are included
  in the PM cache.

v1->v2:
- Patches 1, 3, 4, and 5 are new.
- Patch 2 has been updated to include a dedicated cache for SR registers
  as pointed by sashiko.dev.

Cheers,
Prabhakar
