- * Freescale IMX51 IOMUX Controller
- Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
- and usage.
- Required properties:
- - compatible: "fsl,imx51-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 imx51 datasheet for the valid pad
- config settings.
- CONFIG bits definition:
