Renesas R-Car sound SRC (= Sampling Rate Converter) has Asynchronous/Synchronous SRC mode. Asynchronous mode is already supported via DPCM. This patch adds Synchronous mode on it. The condition of enabling Synchronous mode are - SoC is clock master - Sound uses SRC - Sound doesn't use DVC - Sound card uses DPCM (= rsrc-card card) amixer set "SRC Out Rate" on aplay xxx.wav & amixer set "SRC Out Rate" 48000 Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-03-07ASoC: rsnd: 1st DMAC dma-names cares subnodeKuninori Morimoto1-0/+13
Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC). And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine. But, in result of DMA ML discussion, 2nd DMAC was concluded that it is not a general purpose DMAC (2nd DMAC is for Device to Device inside sound system). Additionally, current DMAEngine can't support Device to Device, and we don't have correct DT bindings for it at this point. So the easiest solution for it is that move it from DMAEngine to rsnd driver. dma-names on DT was implemented as no difference between 1st / 2nd DMAC's, since rsnd had assumed that both DMACs are implemented as DMAEngine. That style was "src_dst". But now, 2nd DMAC was implemented as non DMAEngine, and it doesn't need dma-names anymore. So, this dma-names rule is no longer needed. And additionally, dma-names was assumed that it has all (= SSI/SSIU/SRC/DVC) nodes under sound node. In upstream code, no SoC/platform is supporting DMA for rsnd driver yet. This means there is no compatible issue if this patch changes dma-names's rule of DT. This patch assumes dma-names for 1st DMAC are tx/rx base, and listed in each SSI/SRC/DVC subnode ex) rcar_sound,dvc { dvc0: dvc@0 { dmas = <&audma0 0xbc>; dma-names = "tx"; }; ... rcar_sound,src { src0: src@0 { ... dmas = <&audma0 0x85>, <&audma1 0x9a>; dma-names = "rx", "tx"; }; ... rcar_sound,ssi { ssi0: ssi@0 { ... dmas = <&audma0 0x01>, <&audma1 0x02>, <&audma0 0x15>, <&audma1 0x16>; dma-names = "rx", "tx", "rxu", "txu"; }; ...

Sound data needs to be sent to R-Car sound SSI when playback. But, there are 2 interfaces for it. 1st is SSITDR/SSIRDR which are mapped on SSI. 2nd is SSIn_BUSIF which are mapped on SSIU. 2nd SSIn_BUSIF is used when DMA transfer, and it is always used if sound data came from via SRC. But, we can use it when SSI+DMA case too. (Current driver is assuming 1st SSITDR/SSIRDR for it) 2nd SSIn_BUSIF can be used as FIFO. This is very helpful/useful for SSI+DMA. But DMA address / DMA ID are not same between 1st/2nd cases. This patch care about these settings.
