-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.
-
-
-Optional properties:
-- cts-override : Override the CTS modem status signal. This signal will
- always be reported as active instead of being obtained from the modem status
- register. Define this if your serial port does not use this pin
-
-Example:
- uart@e0000000 {
- compatible = "cdns,uart-r1p8";
- clocks = <&clkc 23>, <&clkc 40>;
- clock-names = "uart_clk", "pclk";
- reg = <0xE0000000 0x1000>;
- interrupts = <0 27 4>;
- };
