Subject: [PATCH v2 0/7] pinctrl: renesas: rzg2l: Unify OEN handling

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

Hi all,

This series unifies the OEN handling in the rzg2l pinctrl driver, allowing
support for RZ/G3E SoC and removing redundant code paths for RZ/G2L,
RZ/V2H, and RZ/V2N SoCs. The changes include
- Parameterizing the OEN register offset to support different SoCs.
- Unifying OEN access functions to use a common pin-to-bit mapping.
- Adding support for RZ/G3E SoC with a new PFC_OEN register.

v1->v2:
- patches 1-5 and 7 are new
- patch 6 has been updated to adopt with the new unified OEN handling

Cheers,
Prabhakar
