| ETRAX FS UART |
| |
| Required properties: |
| - compatible : "axis,etraxfs-uart" |
| - reg: offset and length of the register set for the device. |
| - interrupts: device interrupt |
| |
| Optional properties: |
| - {dtr,dsr,rng,dcd}-gpios: specify a GPIO for DTR/DSR/RI/DCD |
| line respectively. |
| |
| Example: |
| |
| serial@b00260000 { |
| compatible = "axis,etraxfs-uart"; |
| reg = <0xb0026000 0x1000>; |
| interrupts = <68>; |
| status = "disabled"; |
| dtr-gpios = <&sysgpio 0 GPIO_ACTIVE_LOW>; |
| dsr-gpios = <&sysgpio 1 GPIO_ACTIVE_LOW>; |
| rng-gpios = <&sysgpio 2 GPIO_ACTIVE_LOW>; |
| dcd-gpios = <&sysgpio 3 GPIO_ACTIVE_LOW>; |
| }; |
