+* 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>;
+ };
+ };
