From: Fabien Parent <redacted> MSDC1 IP block is powered by VMC. Make sure it is always on.Why always on? Can't you just set mt6357_vmc_reg as VIN of mt6357_vmch_reg? :-)I'm not sure to get it. mt6357_vmc_reg & mt6357_vmch_reg come from PMIC and are supposed to be independent. You suggest to link them in the mt8365-evk dts file using something like: &mt6357_vmch_reg { vin-supply = <&mt6357_vmc_reg>; };
Additionally, vin-supply is supported by fixed-regulator and gpio-regulator, which is not the case here. I think it isn't doable. Regards, Alex
