++* 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;
++};
