The code has a functional dependency to: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg108199.html
Without the above patch the audio card does not probe.
The code has been rebased on top of Linux 3.16 merged with git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next with http://www.mail-archive.com/linux-omap@vger.kernel.org/msg108199.html cherry-picked on top.
All patches have gone trough some cleaning up since the RFC version of these patches over half a year ago.
ps. I forgot to send these patches to alsa-devel@alsa-project.org first time around. The original mailing can be found here: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg108229.html
