On S2MPS14 the LDO10, LDO11 and LDO12 can be configured to external control

over GPIO. To turn this feature on this property must be added to the regulator

sub-node:

	- samsung,ext-control-gpios: GPIO specifier for one GPIO

		controlling this regulator (enable/disable);

Example:

	LDO12 {

		regulator-name = "V_EMMC_2.8V";

		regulator-min-microvolt = <2800000>;

		regulator-max-microvolt = <2800000>;

		samsung,ext-control-gpios = <&gpk0 2 0>;

	};
