GPIO controlled regulators
Required properties:
- compatible : Must be "regulator-gpio".
- states : Selection of available voltages and GPIO configs.
if there are no states, then use a fixed regulator
Optional properties:
- enable-gpio : GPIO to use to enable/disable the regulator.
- gpios : GPIO group used to control voltage.
- startup-delay-us : Startup time in microseconds.
- enable-active-high : Polarity of GPIO is active high (default is low).
Any property defined as part of the core regulator binding defined in
regulator.txt can also be used.
Example:
mmciv: gpio-regulator {
compatible = "regulator-gpio";
regulator-name = "mmci-gpio-supply";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <2600000>;
regulator-boot-on;
enable-gpio = <&gpio0 23 0x4>;
gpios = <&gpio0 24 0x4
&gpio0 25 0x4>;
states = <1800000 0x3
2200000 0x2
2600000 0x1
2900000 0x0>;
startup-delay-us = <100000>;
enable-active-high;
};

Versatile Express voltage regulators
------------------------------------
Requires node properties:
- "compatible" value: "arm,vexpress-volt"
- "arm,vexpress-sysreg,func" when controlled via vexpress-sysreg
(see Documentation/devicetree/bindings/arm/vexpress-sysreg.txt
for more details)
Required regulator properties:
- "regulator-name"
- "regulator-always-on"
Optional regulator properties:
- "regulator-min-microvolt"
- "regulator-max-microvolt"
See Documentation/devicetree/bindings/regulator/regulator.txt
for more details about the regulator properties.
When no "regulator-[min|max]-microvolt" properties are defined,
the device is treated as fixed (or rather "read-only") regulator.
Example:
volt@0 {
compatible = "arm,vexpress-volt";
arm,vexpress-sysreg,func = <2 0>;
regulator-name = "Cores";
regulator-min-microvolt = <800000>;
regulator-max-microvolt = <1050000>;
regulator-always-on;
};
