* 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:
- codec: Contain the Audio Codec node.
  - adc-port: Contain PMIC SSI port number used for ADC.
  - dac-port: Contain PMIC SSI port number used for DAC.
- leds : Contain the led nodes and initial register values in property
  "led-control". Number of register depends of used IC, for MC13783 is 6,
  for MC13892 is 4, for MC34708 is 1. See datasheet for bits definitions of
  these registers.
  - #address-cells: Must be 1.
  - #size-cells: Must be 0.
  Each led node should contain "reg", which used as LED ID (described below).
  Optional properties "label" and "linux,default-trigger" is described in
  Documentation/devicetree/bindings/leds/common.txt.
- regulators : Contain the regulator nodes. The regulators are bound using
  their names as listed below with their registers and bits for enabling.
