+Freescale Kinetis IOMUX Controller
+
+This controller is largely based on i.MX IOMUX Controller. Please refer to
+fsl,imx-pinctrl.txt in this directory for more detailed description.
+
+Required properties:
+- compatible: Should be "fsl,kinetis-iomuxc".
+- reg: Should contain the physical address and length of the gpio/pinmux
+  register range.
+- clocks: Clock that drives this I/O port.
+- 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
+  such as pull enable, pull select, drive strength enable. Please refer to
+  Kinetis datasheet for the valid pad config settings.
+
+Example:
+
+portE: pinmux@4004d000 {
+	compatible = "fsl,kinetis-padconf";
+	reg = <0x4004d000 0x1000>;
+	clocks = <&mcg CLOCK_PORTE>;
+	uart2 {
+		uart2_pins: pinmux_uart2_pins {
+			fsl,pins = <
+				16	0x300 /* E.16 = UART2_TX */
+				17	0x300 /* E.17 = UART2_RX */
+			>;
+		};
+	};
+};
