root@colibri-imx7-emmc:~# ls /dev/ | grep spi
spidev2.0

I have previously commited a mistake of making changes in imx7-colibri-eval-v3.dtsi file instead of imx7-colibri-emmc-eval-v3.dtsi file.

I have a file in /dev folder named spidev2.0

I still am not able to find spidev folder in /dev directory.

Kindly guide me.

Thanks for the information. You have the spidev2.0 under /dev folder as described here. SpidevX.Y means Xth Spi Channel and Yth Chip Select.
So everything is well configured and you can start using the Spi Output for your application.

I am not able to understand the use of spidev2.0. Kindly share an detailed explanation of implementing SpidevX.Y.
