-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>;
-};
