1Binding for Cadence UART Controller
2
3Required properties:
4- compatible :
5 Use "xlnx,xuartps","cdns,uart-r1p8" for Zynq-7xxx SoC.
6 Use "xlnx,zynqmp-uart","cdns,uart-r1p12" for Zynq Ultrascale+ MPSoC.
7- reg: Should contain UART controller registers location and length.
8- interrupts: Should contain UART controller interrupts.
9- clocks: Must contain phandles to the UART clocks
10 See ../clocks/clock-bindings.txt for details.
11- clock-names: Tuple to identify input clocks, must contain "uart_clk" and "pclk"
12 See ../clocks/clock-bindings.txt for details.

15Example:
16 uart@e0000000 {
17 compatible = "cdns,uart-r1p8";
18 clocks = <&clkc 23>, <&clkc 40>;
19 clock-names = "uart_clk", "pclk";
20 reg = <0xE0000000 0x1000>;
21 interrupts = <0 27 4>;
22 };
