Blackfin ASoC drivers with multi-component

Blackfin ASoC drivers with multi-component

[Mark Brown]

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.

Hi Mark,

Thanks for your kind reminder,I will return to audio driver development.
See you soon.

Hi Mark,

We are busy with 2010R1 Linux on blackfin release based on kernel 2.6.34. There is no activity in ADI on multi component audio drivers in latest 2.6.37 rc kernel. However, we are switching to the 2011 development cycle soon, which will cover some audio drivers on top of the multi-component framework.

Please bear in mind that 2.6.37 will be released probably around the end
of next month so it's important to get testing and any fixes done before
then.
