   1 Binding for Cadence UART Controller
   2
   3 Required properties:
   4 - compatible : should be "cdns,uart-r1p8", or "xlnx,xuartps"
   5 - reg: Should contain UART controller registers location and length.
   6 - interrupts: Should contain UART controller interrupts.
   7 - clocks: Must contain phandles to the UART clocks
   8   See ../clocks/clock-bindings.txt for details.
   9 - clock-names: Tuple to identify input clocks, must contain "uart_clk" and "pclk"
  10   See ../clocks/clock-bindings.txt for details.

  14         uart@e0000000 {
  15                 compatible = "cdns,uart-r1p8";
  16                 clocks = <&clkc 23>, <&clkc 40>;
  17                 clock-names = "uart_clk", "pclk";
  18                 reg = <0xE0000000 0x1000>;
  19                 interrupts = <0 27 4>;
