* BCM2835 AUXILIAR UART

Required properties:

- compatible: "brcm,bcm2835-aux-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.

Example:

	uart1: serial@7e215040 {
		compatible = "brcm,bcm2835-aux-uart";
		reg = <0x7e215040 0x40>;
		interrupts = <1 29>;
		clocks = <&aux BCM2835_AUX_CLOCK_UART>;
	};
