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>;
};
