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>;
