+* 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>;
+ };
