- 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>;
- };
