+* Freescale i.MX7 Dual IOMUX Controller
+
+Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
+and usage.
+
+Required properties:
+- compatible: "fsl,imx7d-iomuxc"
+- fsl,pins: each entry consists of 6 integers and represents the mux and config
+ setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
+ input_val> are specified using a PIN_FUNC_ID macro, which can be found in
+ imx7d-pinfunc.h under device tree source folder. The last integer CONFIG is
+ the pad setting value like pull-up on this pin. Please refer to i.MX7 Dual
+ Reference Manual for detailed CONFIG settings.
