| | | | | | | | | | | | | | | | Replace duplicated const keyword for 'dvc_ramp_rate' with proper array of const pointers to const strings. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* | ASoC: rsnd: 1st DMAC dma-names cares subnodeKuninori Morimoto2015-03-071-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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"; }; ...

* ASoC: rsnd: call missing snd_ctl_remove()Kuninori Morimoto2015-02-021-0/+15
| | | | | | | | | | | | Current Renesas R-Car sound driver is using snd_ctl_xxx() functions, but it didn't call snd_ctl free_one() / snd_ctl_remove(). This patch call these functions.

* ASoC: rsnd: save priv in struct rsnd_daiKuninori Morimoto2015-01-151-1/+1
| | | | | | | | | | | Current rsnd driver has rsnd_mod_to_priv() macro, and struct rsnd_mod has struct rsnd_priv pointer. But, it is waste of memory from data structure point of view. Today we can link mod <-> io <-> rdai each other, so saving priv in rdai is very reasonable.

* ASoC: rsnd: replace rdai to priv in each functionKuninori Morimoto2015-01-151-8/+5
| | | | | | | | Current rsnd driver's function requests rdai, but it is not used. Adding priv is more reasonable. Let's replace it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

| | | | | | | | | Current rsnd driver's many functions requests struct rsnd_dai (= rdai), but, 1) we can get rdai from rsnd_io_to_rsnd(), 2) almost all rdai is not used. Let's remove these rdai.
