+* Broadcom BCM6318 pin controller
+
+Required properties:
+- compatible: Must be "brcm,bcm6318-pinctrl".
+- regs: Register specifiers of dirout, dat, mode, mux, and pad registers.
+- reg-names: Must be "dirout", "dat", "mode", "mux", "pad".
+- gpio-controller: Identifies this node as a gpio controller.
+- #gpio-cells: Must be <2>.
+
+Example:
+
+pinctrl: pin-controller@10000080 {
+	compatible = "brcm,bcm6318-pinctrl";
+	reg = <0x10000080 0x08>,
+	      <0x10000088 0x08>,
+	      <0x10000098 0x04>,
+	      <0x1000009c 0x0c>,
+	      <0x100000d4 0x18>;
+	reg-names = "dirout", "dat", "mode", "mux", "pad";
+
+	gpio-controller;
+	#gpio-cells = <2>;
+};
