- * 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:
- - {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD
- line respectively.
- 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>;
- cts-gpios = <&sysgpio 0 GPIO_ACTIVE_LOW>;
- dsr-gpios = <&sysgpio 1 GPIO_ACTIVE_LOW>;
- dcd-gpios = <&sysgpio 2 GPIO_ACTIVE_LOW>;
- };
