1Fixed Voltage regulators
2
3Required properties:
4- compatible: Must be "regulator-fixed";
5- regulator-name: Defined in regulator.txt as optional, but required here.
6
7Optional properties:
8- gpio: gpio to use for enable control
9- startup-delay-us: startup time in microseconds
10- enable-active-high: Polarity of GPIO is Active high
11If this property is missing, the default assumed is Active low.
12- gpio-open-drain: GPIO is open drain type.
13  If this property is missing then default assumption is false.
14-vin-supply: Input supply name.
15
16Any property defined as part of the core regulator
17binding, defined in regulator.txt, can also be used.
18However a fixed voltage regulator is expected to have the
19regulator-min-microvolt and regulator-max-microvolt
20to be the same.

22Example:
23
24	abc: fixedregulator@0 {
25		compatible = "regulator-fixed";
26		regulator-name = "fixed-supply";
27		regulator-min-microvolt = <1800000>;
28		regulator-max-microvolt = <1800000>;
29		gpio = <&gpio1 16 0>;
30		startup-delay-us = <70000>;
31		enable-active-high;
32		regulator-boot-on;
33		gpio-open-drain;
34		vin-supply = <&parent_reg>;
35	};
