2015-11-16ASoC: rsnd: disable SRC.out only when stop timingKuninori Morimoto1-2/+16
Because SRC is connected to DMA and DMA want to keep dreq when stop timing. This patch makes SRC stop SRC.out only when stop timing. And it stops both SRC.out/SRC.in when quit timing Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-11-16ASoC: rsnd: move rsnd_src_ssi_irq_enable/disable() to ssi.cKuninori Morimoto1-28/+0
Part of SSI IRQ enable/disable was controlled by SRU (on Gen1) or CMD (on Gen2). Because of this reason SSI IRQ function was implemented under src.c. but it is not understandable.

2015-11-16ASoC: rsnd: rename rsnd_dma_init() to rsnd_dma_attach()Kuninori Morimoto1-1/+1
Renesas sound needs many devices (SSI/SSIU/SRC/CTU/MIX/DVC/CMD/AudioDMAC/AudioDMACpp). SSI/SRC/CTU/MIX/DVC are implemented as module. SSI parent, SSIU are implemented as part of SSI CMD is implemented as part of CTU/MIX/DVC AudioDMAC/AudioDMACpp are implemented as part of SSI/SRC It is nice sense that these all devices are implemented as mod. DMA will be implemented as module. Then each rsnd_dma_ops will be rsnd_mod_ops. But current rsnd_dma_ops::init means "DMA attach". This patch removes .init from rsnd_dma_ops, and renames rsnd_dma_init() to rsnd_dma_attach() Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-10-14ASoC: rsnd: Announce for removing Gen1 SRU supportKuninori Morimoto1-1/+3
Gen1 SRU support was created for preparation of Gen2 SRC support, but no-one is using this feature (sampling rate convert) on Gen1. BockW had used SRU before, but it was pass through mode. This means it is same as SSI. And BockW "platform base" code was removed from upstream code. It is now supported via DT, but it doesn't use SRU. More detail, r8a7778.dtsi has "rcar_sound,src" entry, but no-one is using this feature today. SRU probing has no relation to this removing. This means there is no effect for DT compatibility, no issues on upstream kernel. Gen2 SRC was created from Gen1 SRU, these are similar but not same IP. Keeping Gen1 SRU in current driver is a little bit difficult, and no-one is using it today. Gen1 sound is still supported via SSI. Gen1 SRU support will be removed in the next kernel version.

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"; }; ...

Current src.c sets SRC_ROUTE_MODE0 on rsnd_src_start(), but, set it in rsnd_src_set_convert_rate() is natural. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Current src initialize SRC on rsnd_src_set_convert_rate() but, it should be done on rsnd_src_init(). Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
