| 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. |
