[v3] MT8196 GPU Frequency/Power Control Support

[PATCH v3 03/10] dt-bindings: sram: Add compatible for mediatek,mt8196-gpufreq-sram

Posted by Nicolas Frattaroli 2 weeks ago

This compatible is used for an SRAM section that's shared between the
MT8196's application processor cores and the embedded GPUEB MCU that
controls the GPU frequency.

Through this SRAM section, things about the GPU frequency controller
like the OPP table can be read.
