The GPU in MT8390 & MT8188 has two power inputs: "DVDD_GPU" and "DVDD_SRAM_GPU". In Genio 700 EVK, DVDD_GPU is supplied by mt6359_vproc2_buck_reg, and DVDD_SRAM_GPU is supplied by mt6359_vsram_others_ldo_reg. According to section 5.2 "Recommended Operating Conditions" in MT8390 IoT Application Processor Datasheet v1.9, The recommended operating voltage ranges are: - DVDD_GPU: min 0.55V, max 0.86V, typical 0.75V - DVDD_SRAM_GPU: min 0.71V, max 0.92V, typical 0.85V In this commit, we set DVDD_SRAM_GPU to typical 0.85V. It is possbile to couple it to the DVDD_GPU in future patches.
