This patch set adds kctrl interface "SSI Out/In BUSIF", which enables to configure busif for each dai-stream used in transfer. device tree files are updated to use extended audio dmac register, and add dma request number for busif1 ~ busif7 Jiada Wang (10): ASoC: rsnd: ssi: Request dedicated dma channels for busif1 to 7 arm64: r8a7795: add dma request number for busif1 ~ busif7 arm64: r8a7796: add dma request number for busif1 ~ busif7 arm64: r8a774a1: add dma request number for busif1 ~ busif7 arm64: r8a7795: change to use extended audio dmac register arm64: r8a7796: change to use extended audio dmac register arm64: r8a774a1: change to use extended audio dmac register arm64: r8a77965: change to use extended audio dmac register ASoC: rsnd: add busif property to dai stream ASoC: rsnd: Add kctrl to configure dai's busif arch/arm64/boot/dts/renesas/r8a774a1.dtsi | 139 ++++++++++++++++++---- arch/arm64/boot/dts/renesas/r8a7795.dtsi | 132 +++++++++++++++++--- arch/arm64/boot/dts/renesas/r8a7796.dtsi | 138 +++++++++++++++++---- arch/arm64/boot/dts/renesas/r8a77965.dtsi | 2 +- sound/soc/sh/rcar/core.c | 16 ++- sound/soc/sh/rcar/dma.c | 32 +++++ sound/soc/sh/rcar/rsnd.h | 5 + sound/soc/sh/rcar/ssi.c | 56 +++++++-- 8 files changed, 451 insertions(+), 69 deletions(-) -- 2.17.0
