* Cirrus Logic CLPS711X Universal Asynchronous Receiver/Transmitter (UART)
|
|
|
|
Required properties:
|
|
- compatible: Should be "cirrus,clps711x-uart".
|
|
- reg: Address and length of the register set for the device.
|
|
- interrupts: Should contain UART TX and RX interrupt.
|
|
- clocks: Should contain UART core clock number.
|
|
- syscon: Phandle to SYSCON node, which contain UART control bits.
|
|
|
|
Optional properties:
|
|
- uart-use-ms: Indicate the UART has modem signal (DCD, DSR, CTS).
|
|
|
|
Note: Each UART port should have an alias correctly numbered
|
|
in "aliases" node.
|
|
|
|
Example:
|
|
aliases {
|
|
serial0 = &uart1;
|
|
};
|
|
|
|
uart1: uart@80000480 {
|
|
compatible = "cirrus,clps711x-uart";
|
|
reg = <0x80000480 0x80>;
|
|
interrupts = <12 13>;
|
|
clocks = <&clks 11>;
|
|
syscon = <&syscon1>;
|
|
uart-use-ms;
|
|
};
