1* BCM63xx UART
2
3Required properties:
4
5- compatible: "brcm,bcm6345-uart"
6
7- reg: The base address of the UART register bank.
8
9- interrupts: A single interrupt specifier.
10
11- clocks: Clock driving the hardware; used to figure out the baud rate
12 divisor.
13
14
15Optional properties:
16
17- clock-names: Should be "refclk".
18
19Example:
20
21 uart0: serial@14e00520 {
22 compatible = "brcm,bcm6345-uart";
23 reg = <0x14e00520 0x18>;
24 interrupt-parent = <&periph_intc>;
25 interrupts = <2>;
26 clocks = <&periph_clk>;
27 clock-names = "refclk";
28 };
29
30 clocks {
31 periph_clk: periph_clk@0 {
32 compatible = "fixed-clock";
33 #clock-cells = <0>;
34 clock-frequency = <54000000>;
35 };
36 };
