From: "hugh.kang" <hugh.kang@lge.com>
If a regulator is set by always-on option, the regulator will be set forever. For example, suppose LDO1 is set to always-on at RevA.dts with including of a.dtsi. After that RevB.dts may wants to include the same a.dtsi but override the LDO1 always-on option. However, currently there is no way to delete the always-on option, even when we change the LDO1 option value, the always-on setting is still remains.
