0001 * Freescale MC13783/MC13892 Power Management Integrated Circuit (PMIC)
0002
0003 Required properties:
0004 - compatible : Should be "fsl,mc13783" or "fsl,mc13892"
0005
0006 Optional properties:
0007 - fsl,mc13xxx-uses-adc : Indicate the ADC is being used
0008 - fsl,mc13xxx-uses-codec : Indicate the Audio Codec is being used
0009 - fsl,mc13xxx-uses-rtc : Indicate the RTC is being used
0010 - fsl,mc13xxx-uses-touch : Indicate the touchscreen controller is being used
0011
0012 Sub-nodes:
0013 - codec: Contain the Audio Codec node.
0014 - adc-port: Contain PMIC SSI port number used for ADC.
0015 - dac-port: Contain PMIC SSI port number used for DAC.
0016 - leds : Contain the led nodes and initial register values in property
0017 "led-control". Number of register depends of used IC, for MC13783 is 6,
0018 for MC13892 is 4, for MC34708 is 1. See datasheet for bits definitions of
0019 these registers.
0020 - #address-cells: Must be 1.
0021 - #size-cells: Must be 0.
0022 Each led node should contain "reg", which used as LED ID (described below).
0023 Optional properties "label" and "linux,default-trigger" is described in
0024 Documentation/devicetree/bindings/leds/common.txt.
0025 - regulators : Contain the regulator nodes. The regulators are bound using
0026 their names as listed below with their registers and bits for enabling.
