-* 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>;
- };
- };
