SPI on i.mx23

Hi all,

Firstly I apologise for what is most probably a stupid question.

Essentially i want to be able to interface with the SP Interface on the i.mx23 evk board. We are creating a custom breakout board for the 120-pin external connector to be able to connect to the SPI pins directly, however, i cannot figure out how to actually interface to these ports in the code itself. I have looked through the kernel source code, and located many references to SPI firmware/drivers, but nevertheless am still unsure of how to proceed. I was mostly looking for pre-defined functions for accessing the ports, or if they dont exist, just the hex addresses of the ports so i can write my own. If its relevant, the pins on the 120-pin connecter i am trying interface to, are 104, 108, 112 and 118.


Any help and/or insight anyone could give me would be great!
