    1 * BCM63xx UART
    2 
    3 Required 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 
   15 Optional properties:
   16 
   17 - clock-names: Should be "refclk".
   18 
   19 Example:
   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         };
