[alsa-devel] [PATCH v5 0/6] core: add compress data API to ALSA kernel

[Vinod Koul]

As agreed during the ASoC workshop in May 2011, this set of patches are a
proposal from Intel to add a new compressed data interface to ALSA. This
proposal builds on the existing Intel solution and the experience gathered over
two years with Meego and Android solutions. This proposal is no longer
Intel-specific and was generalized with the addition of a basic core;
codec-related definitions are based on the vendor-neutral OpenMAX AL standard. 

These patches are also available in git tree:
