You mean spidev?

I'm not sure I follow. If you have used spidev this means the kernel
driver is working just fine. Spidev is simply a user-mode interface for
the kernel's spi subsystem. If you are looking for the driver for the
McSPI controller, this is found in drivers/spi/omap2_mcspi.c.

Do you want to use the spi subsystem from a kernel mode driver? I would
recommend that you take a look at the documentation in
Documentation/spi.

Cheers,
