Here below an example of device tree configuration used on standard DAVE's kit for the [[AXEL ULite SOM]]:
From the Carrier <code>imx6ul-lynxaxelulite-som0013-cb002fcb003a.dts</code> device tree:

pinctrl-0 = <&pinctrl_uart2_flowpinctrl_uart3>; fsl,uart-has-rtscts;

pinctrl-names = "default";
pinctrl-0 = <&pinctrl_hog_gpios>;

For example, using a loopback HW connection (RX short circuited to TX on UART232 port) it is possible to test the send and receive data using the <code>ttymxc2</code> device:
