3Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
4and usage.

6Required properties:
7- compatible: "fsl,imx6ul-iomuxc" for main IOMUX controller or
8  "fsl,imx6ull-iomuxc-snvs" for i.MX 6ULL's SNVS IOMUX controller.
9- fsl,pins: each entry consists of 6 integers and represents the mux and config
10  setting for one pin.  The first 5 integers <mux_reg conf_reg input_reg mux_val
11  input_val> are specified using a PIN_FUNC_ID macro, which can be found in
12  imx6ul-pinfunc.h under device tree source folder.  The last integer CONFIG is
13  the pad setting value like pull-up on this pin.  Please refer to i.MX6 UltraLite
14  Reference Manual for detailed CONFIG settings.
