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.
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
};

Voltage/Current Regulators
Optional properties:
- regulator-name: A string used as a descriptive name for regulator outputs
- regulator-min-microvolt: smallest voltage consumers may set
- regulator-max-microvolt: largest voltage consumers may set
- regulator-microvolt-offset: Offset applied to voltages to compensate for voltage drops
- regulator-min-microamp: smallest current consumers may set
- regulator-max-microamp: largest current consumers may set
- regulator-always-on: boolean, regulator should never be disabled
- regulator-boot-on: bootloader/firmware enabled regulator
- <name>-supply: phandle to the parent supply/regulator node
Example:
xyzreg: regulator@0 {
regulator-min-microvolt = <1000000>;
regulator-max-microvolt = <2500000>;
regulator-always-on;
vin-supply = <&vin>;
};
Regulator Consumers:
Consumer nodes can reference one or more of its supplies/
regulators using the below bindings.
- <name>-supply: phandle to the regulator node
These are the same bindings that a regulator in the above
example used to reference its own supply, in which case
its just seen as a special case of a regulator being a
consumer itself.
Example of a consumer device node (mmc) referencing two
regulators (twl_reg1 and twl_reg2),
twl_reg1: regulator@0 {
...
...
...
};
twl_reg2: regulator@1 {
...
...
...
};
mmc: mmc@0x0 {
...
...
vmmc-supply = <&twl_reg1>;
vmmcaux-supply = <&twl_reg2>;
};

struct regulator_dev *regulator_register(struct regulator_desc *regulator_desc,
