1* Cirrus Logic CLPS711X Universal Asynchronous Receiver/Transmitter (UART)
2
3Required properties:
4- compatible: Should be "cirrus,clps711x-uart".
5- reg: Address and length of the register set for the device.
6- interrupts: Should contain UART TX and RX interrupt.
7- clocks: Should contain UART core clock number.
8- syscon: Phandle to SYSCON node, which contain UART control bits.
9
10Optional properties:
11- uart-use-ms: Indicate the UART has modem signal (DCD, DSR, CTS).
12
13Note: Each UART port should have an alias correctly numbered
14in "aliases" node.
15
16Example:
17 aliases {
18 serial0 = &uart1;
19 };
20
21 uart1: uart@80000480 {
22 compatible = "cirrus,clps711x-uart";
23 reg = <0x80000480 0x80>;
24 interrupts = <12 13>;
25 clocks = <&clks 11>;
26 syscon = <&syscon1>;
27 uart-use-ms;
28 };
