* 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>; };
