Add a couple of missing required properties; add the new optional
properties and an example.

PXA UART controller
Required properties:
-- compatible : should be "mrvl,mmp-uart" or "mrvl,pxa-uart".
+- compatible : should be "mrvl,mmp-uart", "mrvl,pxa-uart", or
+ "brcm,bcm7401-uart".
+- interrupts : a single interrupt specifier.
+- clocks : phandle to a clock; used to compute the baud divisor.
+
+Optional properties:
+- fifo-size : defaults to 64 bytes.
+- big-endian : always use BE register accesses.
+- native-endian : use BE register accesses if the kernel was built for BE,
+ otherwise use LE register accesses.
+
+Example:
+
+ clocks {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ uart_clk: uart_clk@0 {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <81000000>;
+ };
+ };
+
+ uart0: serial@10406900 {
+ compatible = "brcm,bcm7401-upg-uart";
+ reg = <0x10406900 0x20>;
+ native-endian;
+ fifo-size = <32>;
+ interrupt-parent = <&periph_intc>;
+ interrupts = <64>;
+ clocks = <&uart_clk>;
+ };
