For starters, no new drivers should be written aimed at drivers/ide,
libata is what you should be working with instead, aiming your driver at
drivers/ata (you can see many other pata drivers there for examples on
getting started, including ones that deal with ATAPI).

All of the libata documentation is in-kernel, and you can generate pdfs
with 'make pdfdocs', or you can just read through the DocBook file in
Documentation/DocBook/libata.tmpl.

If you run in to further issues, you may also wish to subscribe to or Cc
the linux-ide@vger.kernel.org mailing list, where all IDE and libata
related discussion takes place:
