This series converts davinci ASoC to use genalloc and enables that support on DA850. It applies on top of the uio_pruss/genalloc series [1] which allows DaVinci to provide a gen_pool via pdata for driver use.

I've tested this on the AM180x EVM. Note that prior to this, the SRAM paths in the driver were completely unused. I've only enabled ping-pong buffering on the platform I can test as it's best to allow those with DM644x and similar platforms to set the playback/capture sram size to something that's known to work for them.

Tested on DA850 EVM after applying patches from [1] above. Tested on Linux-torvalds 3.6-rc6 master branch. Tested ASoC module (aplay & arecord for various frequencies)

As you're on it, could you also quickly merge this branch

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git topic/davinci

And see if my recent patches for more McASP flexibility cause any trouble on your hardware?

I have merged it with 3.6-rc6 and I have got error at compile time. I have fixed this locally with the following patch [1]. Kindly confirm if the patch is correct?

I did the same thing locally, but I considered this a merge conflict.

With that Tested on DA850 EVM Tested on Linux-torvalds 3.6-rc6 master branch merged + [1] Tested ASoC module (aplay & arecord for various frequencies)

Ok, that's good to hear. Thanks a lot :)
