Gated Clock Controller Bindings for MIPS based BCM63XX SoCs

Required properties:
- compatible: must be one of:
	 "brcm,bcm3368-clocks"
	 "brcm,bcm6328-clocks"
	 "brcm,bcm6358-clocks"
	 "brcm,bcm6362-clocks"
	 "brcm,bcm6368-clocks"
	 "brcm,bcm63268-clocks"

- reg: Address and length of the register set
- #clock-cells: must be <1>


Example:

clkctl: clock-controller@10000004 {
	compatible = "brcm,bcm6328-clocks";
	reg = <0x10000004 0x4>;
	#clock-cells = <1>;
};
