* Cirrus Logic CLPS711X Universal Asynchronous Receiver/Transmitter (UART)
Required properties:
- compatible: Should be "cirrus,ep7209-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,ep7312-uart","cirrus,ep7209-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>;
};
