Kernel-3.10.0-957.el7_fixed-regulator

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.

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>;
};
