-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>;
- };
