Fixed Voltage regulators



Required properties:

- compatible: Must be "regulator-fixed";

- regulator-name: Defined in regulator.txt as optional, but required here.



Optional properties:

- gpio: gpio to use for enable control

- startup-delay-us: startup time in microseconds

- enable-active-high: Polarity of GPIO is Active high

If this property is missing, the default assumed is Active low.

- gpio-open-drain: GPIO is open drain type.

  If this property is missing then default assumption is false.

-vin-supply: Input supply name.



Any property defined as part of the core regulator

binding, defined in regulator.txt, can also be used.

However a fixed voltage regulator is expected to have the

regulator-min-microvolt and regulator-max-microvolt

to be the same.



Example:



	abc: fixedregulator@0 {

		compatible = "regulator-fixed";

		regulator-name = "fixed-supply";

		regulator-min-microvolt = <1800000>;

		regulator-max-microvolt = <1800000>;

		gpio = <&gpio1 16 0>;

		startup-delay-us = <70000>;

		enable-active-high;

		regulator-boot-on;

		gpio-open-drain;

		vin-supply = <&parent_reg>;

	};
