Re: [alsa-devel] [PATCH] ASoC: rsnd: dma: set bus width to data width for monaural data

Hi

According to R-Car3 HW manual 40.3.3 (Data Format on Audio Local Bus), in case of monaural data writing or reading through Audio-DMAC, it's always in Left Justified format, so both src and dst DMA Bus width should be equal to physical data width.

Therefore set src and dst's DMA bus width to:

• [monaural case] data width
• [non-monaural case] 32bits (as prior applying the patch)

I don't know how Monaural works, but I know you are using it. Thus don't say Acked-by and/or Reviewed-by, but I have no objection about this patch.

Thank you for your help !! Best regards --- Kuninori Morimoto
