Look at any of the existing ppi drivers - and use one of those to based your driver from.

If you have not used Linux before, start at:

http://docs.blackfin.uclinux.org/doku.php?id=references_and_pointers#intro_to_linux

 

Then go read most of the books lists at:

http://docs.blackfin.uclinux.org/doku.php?id=references_and_pointers#good_books

 

Then go read the existing PPI drivers.

Again - pick a existing ppi driver that is close to what you want to do, and look at that.
