[Kuninori Morimoto]

Hi Mark

I re-post these patches.
Please ignore these patches

> Current Renesas sound driver (= FSI/RSND) is not using
> ALSA common DMAEngine method for some reasons.
> The 1st reason was that Renesas DMA didn't support
> cyclic transfer mode.
> But now, it is supported !
> These patches support cyclic transfer for FSI/RSND
> 
> It needs this branch

> (DMA: shdma: add cyclic transfer support)

> These are based on mark/topic/rcar branch

> Kuninori Morimoto (4):
>       ASoC: fsi: use SNDRV_DMA_TYPE_DEV for sound buffer
>       ASoC: fsi: add fsi_pointer_update() for common pointer method
>       ASoC: fsi: use dmaengine_prep_dma_cyclic() for DMA transfer
>       ASoC: rsnd: use dmaengine_prep_dma_cyclic() instead of original method
