How to enable i2c and SPI module in Intel Agilex Soc

There are few sensor connected to I2C and SPI bus of HPS. I have added device entry in DTS file and appropriately device driver module is also enabled.

However, I am not able to find any device entry in kernel file system.

root@agilex:~# ls /dev/i2c*
ls: cannot access '/dev/i2c*': No such file or directory

Am I missing somethig here?
