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