This patchset is a collection of changes for the davinci-pcm driver that were accumulated during previous forays into the davinci-mcasp and davinci-pcm drivers [1].
The first three patches are minor changes that cleanup the ping-pong DMA params setup, expand the davinci-pcm reported format and also its maximum channels.
The fourth patch in the series corrects an audible glitch that can be heard on da850evm's McASP when ping-pong buffers are enabled. The glitch occurs only on the second and susequent playbacks, not the first. Reversing the order in which the dma channels are started and moving the start to the trigger function from the prepare function fixes the glitch.
The fifth and sixth patches in the series convert the davinci-pcm driver to BATCH mode.

One minor thing for patch 6 that can be added incrementally.
