ASoC: rsnd: enable DVC when capture
Current DVC can be enabled only when playback, but, this came from misunderstanding. It is not correct. DVC <-> DMA relationship is... Playback: MEM -> DMAC -> SRC -> DVC -> DMACp -> SSI Capture: SSI -> DMACp -> SRC -> DVC -> DMAC -> MEM DVC can be used for both Playback/Capture Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
