| * 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. |
