[PATCH 0/3] Add support for Mali-G31 GPU on RZ/V2H(P) SoC

[Prabhakar]

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

Hi All,

This patch series adds support for the Mali-G31 GPU on the RZ/V2H(P) SoC.
The changes include updating the device tree bindings, adding the GPU node
to the SoC device tree, and enabling the GPU on the RZ/V2H evaluation kit.

[PATCH 1/3] dt-bindings: gpu: mali-bifrost: Add compatible for RZ/V2H(P) SoC

[Prabhakar]

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

Add a compatible string for the Renesas RZ/V2H(P) SoC variants that
include a Mali-G31 GPU. These variants share the same restrictions on
interrupts, clocks, and power domains as the RZ/G2L SoC, so extend
the existing schema validation accordingly.
