* BCM63xx UART

Required properties:

- compatible: "brcm,bcm6345-uart"

- reg: The base address of the UART register bank.

- interrupts: A single interrupt specifier.

- clocks: Clock driving the hardware; used to figure out the baud rate
  divisor.


Optional properties:

- clock-names: Should be "refclk".

Example:

	uart0: serial@14e00520 {
		compatible = "brcm,bcm6345-uart";
		reg = <0x14e00520 0x18>;
		interrupt-parent = <&periph_intc>;
		interrupts = <2>;
		clocks = <&periph_clk>;
		clock-names = "refclk";
	};

	clocks {
		periph_clk: periph_clk@0 {
			compatible = "fixed-clock";
			#clock-cells = <0>;
			clock-frequency = <54000000>;
		};
	};
