1 * Cirrus Logic CLPS711X Universal Asynchronous Receiver/Transmitter (UART)
2
3 Required properties:
4 - compatible: Should be "cirrus,ep7209-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
10 Optional properties:
11 - {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD
12 line respectively.
13
14 Note: Each UART port should have an alias correctly numbered
15 in "aliases" node.
16
17 Example:
18 aliases {
19 serial0 = &uart1;
20 };
21
22 uart1: uart@80000480 {
23 compatible = "cirrus,ep7312-uart","cirrus,ep7209-uart";
24 reg = <0x80000480 0x80>;
25 interrupts = <12 13>;
26 clocks = <&clks 11>;
27 syscon = <&syscon1>;
28 cts-gpios = <&sysgpio 0 GPIO_ACTIVE_LOW>;
29 dsr-gpios = <&sysgpio 1 GPIO_ACTIVE_LOW>;
30 dcd-gpios = <&sysgpio 2 GPIO_ACTIVE_LOW>;
31 };
