+ANATOP REGULATOR
+
+Anatop is an integrated regulator inside i.MX6 SoC.
+
+Required properties:
+- compatible: Must be "fsl,anatop-regulator".
+- regulator-name: Name of the regulator
+- anatop-reg-offset: u32 value representing the anatop MFD register offset.
+- anatop-vol-bit-shift: u32 value representing the bit shift for the register.
+- anatop-vol-bit-width: u32 value representing the number of bits used in the
+ register.
+- anatop-min-bit-val: u32 value representing the minimum value of this
+ register.
+- anatop-min-voltage: u32 value representing the minimum voltage of this
+ regulator.
+- anatop-max-voltage: u32 value representing the maximum voltage of this
+ regulator.
+
+Optional properties:
+- anatop-delay-reg-offset: u32 value representing the anatop MFD step time
+ register offset.
+- anatop-delay-bit-shift: u32 value representing the bit shift for the step
+ time register.
+- anatop-delay-bit-width: u32 value representing the number of bits used in
+ the step time register.
+- anatop-enable-bit: u32 value representing regulator enable bit offset.
+- vin-supply: input supply phandle.
+
+Example:
+ regulator-vddpu {
+ compatible = "fsl,anatop-regulator";
+ regulator-name = "vddpu";
+ regulator-min-microvolt = <725000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-always-on;
+ anatop-reg-offset = <0x140>;
+ anatop-vol-bit-shift = <9>;
+ anatop-vol-bit-width = <5>;
+ anatop-delay-reg-offset = <0x170>;
+ anatop-delay-bit-shift = <24>;
+ anatop-delay-bit-width = <2>;
+ anatop-min-bit-val = <1>;
+ anatop-min-voltage = <725000>;
+ anatop-max-voltage = <1300000>;
