Hi Mark

These are DMAEngine support patches for R-Car sound

Last patch cleanups empty SCU functions.
I will work for regmap support soon, but I need more time for it.

This patch doesn't use soc-dmaengine-pcm.c method,
becouse current R-Car chip doesn't suuport dmaengine_prep_dma_cyclic().
Of course I can re-work to use it if chip/rcar-dmaengine supports it.

these are based on mark/topic/rcar branch

Kuninori Morimoto (5):
      ASoC: rsnd: remove platform dai and add dai_id on platform setting
      ASoC: rsnd: add common DMAEngine method
      ASoC: rsnd: SSI supports DMA transfer
      ASoC: rsnd: SSI supports DMA transfer via BUSIF
      ASoC: rsnd: scu: cleanup empty functions
