I have question regarding SPI interface in th linux kernel. I want access SPI device in the user space as well as kernel space.

I found following attached information about SPI which helped me understand SPI system better

I want to keep the spidev interface to access SPI device in the user space and I also want to implement protocol driver in the kernel space.

My query is can spidev driver(userspace) and protocol driver(kernel space) co-exist? If yes, can I access spidev driver and protocol driver simulataneously?



Thanks in advance.


Kind Regards,
Lubna
