++* Broadcom BCM6328 pin controller
++
++Required properties:
++- compatible: Must be "brcm,bcm6328-pinctrl".
++- reg: Register specifies of dirout, dat, mode, mux registers.
++- reg-names: Must be "dirout", "dat", "mode", "mux".
++- gpio-controller: Identifies this node as a GPIO controller.
++- #gpio-cells: Must be <2>
++
++Example:
++
++pinctrl: pin-controller@10000080 {
++ compatible = "brcm,bcm6328-pinctrl";
++ reg = <0x10000080 0x8>,
++ <0x10000088 0x8>,
++ <0x10000098 0x4>,
++ <0x1000009c 0xc>;
++ reg-names = "dirout", "dat", "mode", "mux";
++
++ gpio-controller;
++ #gpio-cells = <2>;
++};
