Here is the much delayed support for compress audio streams in ASoC. This patch series is in RFC form, once we have agreed on this I will send the patches supporting Intel driver as well.
Mainly we indicate if the dai is of compressed nature and based on that register a new compressed device. Also the platform driver adds the compress stream operations. Since the codecs handles PCM only, the assumption is that they will not have anything to do here and machine needs to set codec appropriately for compressed streams. In future if codec with such support are available then we can simply add compressed operations into codec as well
Comments, criticism welcome...
