      ASoC: rsnd: each mod has status again for CTU/MUX support · 5ba17b42
      由 Kuninori Morimoto 提交于 
      SSI will be used as normal SSI or as clock parent SSI. Therefor,
rsnd driver wants to control SSI and parent SSI separately. Otherwise it
can't use Playback/Capture in the same time.
And it has been done by c2dc47d5("ASoC: rsnd: rsnd_dai_stream has each
mod's status insted of rsnd_mod") before.

OTOH, rsnd driver doesn't want to control CTU/MUX/DVC/SSIU/SSI in
separately. Otherwise, these will be re-initialized during playing if
MUX merges 2 sounds.
Because of these picky reasons, this patch re-defines status on each mod,
and add new parent_ssi_status on rsnd_dai_stream.

      ASoC: rsnd: 1st DMAC dma-names cares subnode · 72adc61f
      由 Kuninori Morimoto 提交于 
      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: dvc: add rsnd_dvc_of_node() · 93b986e2
      由 Kuninori Morimoto 提交于 
      This patch adds rsnd_dvc_of_node() to get DVC subnode from DT.
This is prepare for new DT bindings for 1st DMAC
