Kernel-4.18.0-80.el8_cdns,uart

Binding for Cadence UART Controller

Required properties:

• compatible :
  Use “xlnx,xuartps”,”cdns,uart-r1p8” for Zynq-7xxx SoC.
  Use “xlnx,zynqmp-uart”,”cdns,uart-r1p12” for Zynq Ultrascale+ MPSoC.
• reg: Should contain UART controller registers location and length.
• interrupts: Should contain UART controller interrupts.
• clocks: Must contain phandles to the UART clocks
  See ../clocks/clock-bindings.txt for details.
• clock-names: Tuple to identify input clocks, must contain “uart_clk” and “pclk”
  See ../clocks/clock-bindings.txt for details.

Example:
uart@e0000000 {
compatible = “cdns,uart-r1p8”;
clocks = <&clkc 23>, <&clkc 40>;
clock-names = “uart_clk”, “pclk”;
reg = <0xE0000000 0x1000>;
interrupts = <0 27 4>;
};
