Re: [alsa-devel] [RFC PATCH v3 0/3] ep93xx i2s audio

The following patch series adds support for i2s audio on the ep93xx, with the Snapper CL15 used as an example implementation.

This version fixes a number of things from the previous round:

• Removed unused #defines
• Set symmetric rates for the cpu dai
• Fixed the sdiv/lrdiv calculation loop
• Moved the cpu dai registration
• Removed empty ep93xx_pcm_prepare callback
• Fixed enable/disable when both capture and playback are running

Capture still does not work. The dma is running, but the captured data is all zeros (tested used arecord and loopback). I have a 2.6.20 kernel with ep93xx i2s audio working an capture works there on the same hardware. I have spent sometime looking into this, but can't see the problem. Would appreciate if someone can lend some insight as to what I have done wrong.
