+Regulators for Freescale i.MX23/i.MX28
+
+Required properties:
+For imx23 regulators
+- compatible:
+ - "fsl,imx23-dcdc" for DC-DC converter
+ - "fsl,imx23-vddd" for VDDD linear regulator
+ - "fsl,imx23-vdda" for VDDA linear regulator
+ - "fsl,imx23-vddio" for VDDIO linear regulator
+For imx28 regulators
+- compatible:
+ - "fsl,imx28-dcdc" for DC-DC converter
+ - "fsl,imx28-vddd" for VDDD linear regulator
+ - "fsl,imx28-vdda" for VDDA linear regulator
+ - "fsl,imx28-vddio" for VDDIO linear regulator
+- reg: Address and length of the register set for the device. It contains
+ the information of registers in the same order as described by reg-names
+- reg-names: Should contain the reg names
+ - "base-address" - contains base address of regulator
+ - "status-address" - contains status address of regulator
+ - "v5ctrl-address" - contains 5V control address of DC-DC converter
+ (required only for linear regulators)
+ - "misc-address" - contains misc control address of DC-DC converter
+ (required only for DC-DC converter)
+
+Optional properties:
+- switching-frequency: switching frequency of the DC-DC converter in Hz.
+ Possible values are <19200000>, <22000000> or <24000000> (default).
+
+Any regulator property defined as part of the core regulator
+binding, defined in regulator.txt, can also be used.
+
+Example for i.MX28:
+
+ power: power@80044000 {
+ compatible = "fsl,imx28-power";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ reg = <0x80044000 0x2000>;
+ interrupts = <6>;
+ ranges;
+
+ dcdc: regulator@80044010 {
+ reg = <0x80044010 0x10>,
+ <0x80044090 0x10>,
+ <0x800440c0 0x10>;
+ reg-names = "base-address",
+ "misc-address",
+ "status-address";
+ compatible = "fsl,imx28-dcdc";
+ regulator-name = "dcdc";
+ regulator-boot-on;
+ regulator-always-on;
+ switching-frequency = <24000000>;
+ };
+
+ reg_vddd: regulator@80044040 {
+ reg = <0x80044040 0x10>,
+ <0x80044010 0x10>,
+ <0x800440c0 0x10>;
+ reg-names = "base-address",
+ "v5ctrl-address",
+ "status-address";
+ compatible = "fsl,imx28-vddd";
+ regulator-name = "vddd";
+ regulator-min-microvolt = <1350000>;
+ regulator-max-microvolt = <1550000>;
+ };
+ };
