Binding for Cadence UART Controller
|
|
|
|
Required properties:
|
|
- compatible : should be "cdns,uart-r1p8", or "xlnx,xuartps"
|
|
- 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>;
|
|
};
