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 availble in git tree: git://git.infradead.org/users/vkoul/snd-compress.git v2_patches
Changes in v2: Fixed the comments revived in v2 Fixed the comments recieved during LPC discussions add support for alsa device registeration fix the bugs found in testing
Omair Mohammed Abdullah (1): core: add support for compressed devices
Vinod Koul (5): compress API documentation compress: add compress parameter definations compress: add API header and driver header files compress: add the core file compress: add makefile and kconfig file
