Thank you for the review.

The driver has of_device_id.

static const struct of_device_id sky81452_reg_of_match[] = {
{ .compatible = "skyworks,sky81452-regulator", },
{ }
};

And the MFD adds the driver with of_compatible="skyworks,sky81452-regulator".
MFD core maps the device node and the regulator driver does
not need to parse the subnode name.

Thanks.
