+* Broadcom BCM6368 pin controller
+
+Required properties:
+- compatible: Must be "brcm,bcm6368-pinctrl".
+- reg: Register specifiers of dirout, dat, mode registers.
+- reg-names: Must be "dirout", "dat", "mode".
+- brcm,gpiobasemode: Phandle to the gpio basemode register.
+- gpio-controller: Identifies this node as a GPIO controller.
+- #gpio-cells: Must be <2>.
+
+Example:
+
+pinctrl: pin-controller@10000080 {
+	compatible = "brcm,bcm6368-pinctrl";
+	reg = <0x10000080 0x08>,
+	      <0x10000088 0x08>,
+	      <0x10000098 0x04>;
+	reg-names = "dirout", "dat", "mode";
+	brcm,gpiobasemode = <&gpiobasemode>;
+
+	gpio-controller;
+	#gpio-cells = <2>;
+};
+
+gpiobasemode: syscon@100000b8 {
+	compatible = "brcm,bcm6368-gpiobasemode", "syscon";
+	reg = <0x100000b8 4>;
+	native-endian;
+};
