ASoC: rsnd: DMA start address is properly used for each DMAC
R-Car sound uses Audio DMAC and Audio DMAC peri peri. Audio DMAC peri peri transfers data inside circuit. DMA transfer needs source / destination address, and destination address can be set via dmaengine_slave_config(). The source address can be set when starting DMAEngine. Because Audio DMAC peri peri always ignores its value, current driver always used same source address for Audio DMAC / Audio DMAC peri peri (Audio DMAC peri peri source / destination address is always fixed value) But, This is not good match for DT booting. This patch properly uses DMA start address for Audio DMAC / Audio DMAC peri peri. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
