This defers the modesetting to the consumer. 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
