6Required 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.
