Changes since v2:
- Constraint only placed for the period size [1]
- Patch for davinci-pcm.h to add empty function in case of !DAVINCI platforms

When the edma arch and dmaengine patches has been taken only one patch is needed
to switch AM335x/AM437x to use the edma-pcm.

[1]. I was not able to reporoduce the issue I have seen with mplayer anymore.
     As it was thought constraint for the period size is enough and there's no
     need to place the same constraint on buffer size.

Peter Ujfalusi (3):
  ASoC: davinci-mcasp: Constraint on the period and buffer size based on
    FIFO usage
  ASoC: davinci-mcasp: Assign the dma_data earlier in dai_probe callback
  ASoC: davinci-pcm: Add empty functions for !CONFIG_SND_DAVINCI_SOC
