+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>;
