   1 * Freescale MC13783/MC13892 Power Management Integrated Circuit (PMIC)
   2
   3 Required properties:
   4 - compatible : Should be "fsl,mc13783" or "fsl,mc13892"
   5
   6 Optional properties:
   7 - fsl,mc13xxx-uses-adc : Indicate the ADC is being used
   8 - fsl,mc13xxx-uses-codec : Indicate the Audio Codec is being used
   9 - fsl,mc13xxx-uses-rtc : Indicate the RTC is being used
  10 - fsl,mc13xxx-uses-touch : Indicate the touchscreen controller is being used
  11
  12 Sub-nodes:
  13 - leds : Contain the led nodes and initial register values in property
  14   "led-control". Number of register depends of used IC, for MC13783 is 6,
  15   for MC13892 is 4, for MC34708 is 1. See datasheet for bits definitions of
  16   these registers.
  17   - #address-cells: Must be 1.
  18   - #size-cells: Must be 0.
  19   Each led node should contain "reg", which used as LED ID (described below).
  20   Optional properties "label" and "linux,default-trigger" is described in
  21   Documentation/devicetree/bindings/leds/common.txt.
  22 - regulators : Contain the regulator nodes. The regulators are bound using
  23   their names as listed below with their registers and bits for enabling.
