I'm a little concerned that there have been no updates to the Blackfin audio drivers since the merge of multi-component ASoC (which is now in mainline and should be released as part of 2.6.37). This was a very big and invasive update, and experience with other architectures has been that there's usually at least some typos that need fixing. It'd be good to get some confirmation that the audio drivers have at least been tested with current mainline - if everything worked fine that's obviously excellent but it'd be good if someone could confirm that this is the case.
There was some discussion with Mike at the time the drivers were merged but it sounded more like "I need to get the audio guys to look at this" than a report of actual testing and there's been nothing since.
