* Freescale IMX6 SoloLite IOMUX Controller

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

Required properties:
- compatible: "fsl,imx6sl-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 imx6sl datasheet for the valid pad
  config settings.
