   6 Required properties:
   7 - compatible: "fsl,imx6sx-iomuxc"
   8 - fsl,pins: each entry consists of 6 integers and represents the mux and config
   9   setting for one pin.  The first 5 integers <mux_reg conf_reg input_reg mux_val
  10   input_val> are specified using a PIN_FUNC_ID macro, which can be found in
  11   imx6sx-pinfunc.h under device tree source folder.  The last integer CONFIG is
  12   the pad setting value like pull-up on this pin.  Please refer to i.MX6 SoloX
  13   Reference Manual for detailed CONFIG settings.
