Hi
I have seen some discussion on the mailing list about upcoming changes in ASoC for soc-dsp support / dynamic PCM.
Could somebody explain what is the purpose of these changes?
Is there a branch where I can have a look to the on-going work?
Thanks
Regards,
Sebastien

The purpose is to support on SoC DSP devices that can route digital
audio from ALSA PCM devices to multiple SoC DAIs at runtime (like OMAP4
ABE).

Sure, my TI lrg/topic/3.5-rebase ABE branch is probably best to take a
look atm as it shows the ABE and DPCM code together.
gitorious.org:omap-audio/linux-audio.git
You can also try the code if you have a Pandaboard.
