|
|
Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
|
|
and usage.
|
|
|
|
Required properties:
|
|
- compatible: "fsl,imx6q-iomuxc"
|
|
- fsl,pins: two integers array, represents a group of pins mux and config
|
|
setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
|
|
pin working on a specific function, CONFIG is the pad setting value like
|
|
pull-up for this pin. Please refer to imx6q datasheet for the valid pad
|
|
config settings.
