Fixed Voltage regulators
Required properties:
- compatible: Must be "regulator-fixed";
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.
