+* Broadcom BCM6362 pin controller
+
+Required properties:
+- compatible: Must be "brcm,bcm6362-pinctrl"
+- reg: Register specifiers of dirout, dat, led, mode, ctrl, basemode registers.
+- reg-names: Must be "dirout", "dat", "led", "mode", "ctrl", "basemode".
+- gpio-controller: Identifies this node as a GPIO controller.
+- #gpio-cells: Must be <2>.
+
+Example:
+
+pinctrl: pin-controller@10000080 {
+	compatible = "brcm,bcm6362-pinctrl";
+	reg = <0x10000080 0x8>,
+	      <0x10000088 0x8>,
+	      <0x10000090 0x4>,
+	      <0x10000098 0x4>,
+	      <0x1000009c 0x4>,
+	      <0x100000b8 0x4>;
+	reg-names = "dirout", "dat", "led",
+		    "mode", "ctrl", "basemode";
+
+	gpio-controller;
+	#gpio-cells = <2>;
+};
