This patch series adds AXD Alsa Compress Offload SoC driver.
AXD is an audio hardware based on MIPS architecture that supports decoding,
encoding, GEQ, resampling, mixing and synchronisation. At the moment only
decoding support is added in hope to add the rest of the functionality on
top of that once this is accepted.
I divided the files into separate patches by functionality in hope it'll
make the reviewing process easier. Worth noting that a lot of the cmd interface
helper funtions in patch 7 are not used yet but will be as support for more
functionality is added later.
At the moment this code has been tested on Pistachio SoC using gstreamer patched
with the code in this link
