The clock "mfg_core_tmp" is only used as an alt clock when setting mfgpll clock rate. If we keep the univpll parents from mfg_core_tmp, when setting GPU frequency to 390000000, the common clock framework would switch the parent to univpll, instead of setting mfgpll to 390000000: mfgpll 0 0 0 949999756 univpll 2 2 0 2340000000 univpll_d6 1 1 0 390000000 top_mfg_core_tmp 1 1 0 390000000 mfg_ck_fast_ref 1 1 0 390000000 mfgcfg_bg3d 1 1 0 390000000 This results in failures when subsequent devfreq operations need to switch to other frequencies.

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 To further optimize power saving, we couple DVDD_SRAM_GPU to DVDD_GPU according to the following relation: - For opp-880000000 or lower frequency, keep 0.75V - For opp-915000000 and higher, DVDD_SRAM_GPU should follow DVDD_GPU. The exact voltage for DVDD_GPU should be decided by speed binning. This rule is derived from the OPP table in the link. In addition, set the voltage spread to 6250 uV, the step size of 'ldo_vsram_others' regulator of mt6359, otherwise the regulator set_voltage operation fails.
