Subject: [PATCH v3 1/3] dt-bindings: gpu: mali-bifrost: Add compatible for
 MT8370 SoC

Add a compatible for the MediaTek MT8370 SoC, with an
integrated ARM Mali G57 MC2 GPU (Valhall-JM, dual core).
This new compatible is needed for this SoC support, as the other
existing compatibles for the same GPU architecture (MT8188, MT8192) do
not match the required power domain number.
The other compatibles (especially MT8186) cannot be reused because of
GPU architecture difference.
