| * 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>; |
| }; |
