Freescale Vybrid VF610 IOMUX Controller



Please refer to fsl,imx-pinctrl.txt in this directory for common binding part

and usage.



Required properties:

- compatible: "fsl,vf610-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

  such as pull-up, speed, ode for this pin. Please refer to Vybrid VF610

  datasheet for the valid pad config settings.
