Please take a look at the qcom-rpmh-regulator driver and implement something like this: static unsigned int rpmh_regulator_vrm_get_optimum_mode( struct regulator_dev *rdev, int input_uV, int output_uV, int load_uA) { struct rpmh_vreg *vreg = rdev_get_drvdata(rdev); if (load_uA >= vreg->hw_data->hpm_min_load_uA) return REGULATOR_MODE_NORMAL; else return REGULATOR_MODE_IDLE; } and fill out the max current allowed for LPM for each regulator Konrad
