| 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>; | |
| 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>; | |
| }; |
