* 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>;
};
};
