+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>;
+ };
