- Freescale IMX35 IOMUX Controller
Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
and usage.
Required properties:
- compatible: “fsl,imx35-iomuxc”
- fsl,pins: two integers array, represents a group of pins mux and config
setting. The format is fsl,pins =, 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 imx35 datasheet for the valid pad
config settings.
