* Freescale MC13783/MC13892 Power Management Integrated Circuit (PMIC)

Required properties:
- compatible : Should be "fsl,mc13783" or "fsl,mc13892"

Optional properties:
- fsl,mc13xxx-uses-adc : Indicate the ADC is being used
- fsl,mc13xxx-uses-codec : Indicate the Audio Codec is being used
- fsl,mc13xxx-uses-rtc : Indicate the RTC is being used
- fsl,mc13xxx-uses-touch : Indicate the touchscreen controller is being used

Sub-nodes:
- regulators : Contain the regulator nodes.  The name of regulator node
  is being used by mc13xxx regulator driver to find the correct relator
  device.

  The bindings details of individual regulator device can be found in:
  Documentation/devicetree/bindings/regulator/regulator.txt

Examples:

ecspi@70010000 { /* ECSPI1 */
	fsl,spi-num-chipselects = <2>;
	cs-gpios = <&gpio3 24 0>, /* GPIO4_24 */
		   <&gpio3 25 0>; /* GPIO4_25 */
	status = "okay";

	pmic: mc13892@0 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "fsl,mc13892";
		spi-max-frequency = <6000000>;
		reg = <0>;
		interrupt-parent = <&gpio0>;
		interrupts = <8>;

		regulators {

				regulator-min-microvolt = <600000>;
				regulator-max-microvolt = <1375000>;
				regulator-boot-on;
				regulator-always-on;
			};

				regulator-max-microvolt = <1850000>;
				regulator-boot-on;
