[PATCH v2 0/4] arm64: dts: renesas: Add I2C and SDHI nodes for RZ/T2H and RZ/N2H SoCs

[Prabhakar]

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

Hi All,

This patch series adds I2C and SDHI nodes for the Renesas RZ/T2H
(R9A09G077) and RZ/N2H (R9A09G087) SoCs. The I2C/SDHI nodes are added
to the respective SoC DTSI files.

SDHI/I2C DT binding patches are already merged in the -next tree:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=next-20250704&id=b93d8b1cab299bc76f574f9e3cb8aafcfafc0037
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=next-20250704&id=ac54e31a205346899ef5646d0456b97179901070

v1->v2:
- Fixed W=1 warnings in the device tree files.
- Fixed clock for i2c2.
- Added "Reviewed-by" tag for patches 2/4 and 3/4.
- Dropped led enabling patches as it depends on the pinctrl driver
  changes which are not yet merged.

Cheers,
Prabhakar
