+* Broadcom BCM6348 pin controller
+
+Required properties:
+- compatible: Must be "brcm,bcm6348-pinctrl".
+- reg: register Specifiers of dirout, dat, mode registers.
+- reg-names: Must be "dirout", "dat", "mode".
+- gpio-controller: Identifies this node as a GPIO controller.
+- #gpio-cells: Must be <2>.

+Example:
+
+pinctrl: pin-controller@fffe0080 {
+ compatible = "brcm,bcm6348-pinctrl";
+ reg = <0xfffe0080 0x8>,
