+* Freescale IMX35 IOMUX Controller
+
+Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
+and usage.
+
+Required properties:
+- compatible: "fsl,imx35-iomuxc"
+- fsl,pins: two integers array, represents a group of pins mux and config
+ setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
+ pin working on a specific function, CONFIG is the pad setting value like
+ pull-up for this pin. Please refer to imx35 datasheet for the valid pad
+ config settings.
+
+CONFIG bits definition:
+PAD_CTL_DRIVE_VOLAGAGE_18 (1 << 13)
+PAD_CTL_DRIVE_VOLAGAGE_33 (0 << 13)
+PAD_CTL_HYS (1 << 8)
+PAD_CTL_PKE (1 << 7)
+PAD_CTL_PUE (1 << 6)
+PAD_CTL_PUS_100K_DOWN (0 << 4)
+PAD_CTL_PUS_47K_UP (1 << 4)
+PAD_CTL_PUS_100K_UP (2 << 4)
+PAD_CTL_PUS_22K_UP (3 << 4)
+PAD_CTL_ODE_CMOS (0 << 3)
+PAD_CTL_ODE_OPENDRAIN (1 << 3)
+PAD_CTL_DSE_NOMINAL (0 << 1)
+PAD_CTL_DSE_HIGH (1 << 1)
+PAD_CTL_DSE_MAX (2 << 1)
+PAD_CTL_SRE_FAST (1 << 0)
+PAD_CTL_SRE_SLOW (0 << 0)
+
+Refer to imx35-pinfunc.h in device tree source folder for all available
+imx35 PIN_FUNC_ID.
