• Freescale i.MX6 UltraLite IOMUX Controller

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

Required properties:

• compatible: “fsl,imx6ul-iomuxc” for main IOMUX controller or
  “fsl,imx6ull-iomuxc-snvs” for i.MX 6ULL’s SNVS IOMUX controller.
• fsl,pins: each entry consists of 6 integers and represents the mux and config
  setting for one pin. The first 5 integers are specified using a PIN_FUNC_ID macro, which can be found in
