The first patch implements McBSP sidetone feature on OMAP3 while the second one provides ALSA interface for using it. The patch set is based on the patch Eduardo Valentin sent to alsa-devel mailing list in October 2009. Channel gain control and enabling the sidetone have been moved to ALSA interface as suggested in comments. These patches apply on top of Janusz Krzysztofik's McBSP register cache patches in linux-omap-2.6.git Since the version 3, the buggy channel gain control has been fixed. ASoC part have been simplified resulting in removing a couple unnecessary functions. Added a comment to ASoC part explaining McBSP port number vs. index values used in OMAP McBSP implementation.
