[PATCH 0/8] ASoC: simple-card: DPCM support

[Kuninori Morimoto <kuninori.morimoto.gx-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Hi Mark

These patches are DPCM support for simple-card,
and milestone is (*)

	* 1. simple DPCM support on DT
	  2. sampling rate convert support on DPCM
	  3. multi FE/BE support on DT
	  4. rsnd multi block IP use multi DPCM

1) - 4) are tidyup patches of simple-card
5) adds DPCM support on simple-card
6) tidyups asoc_simple_card_sub_parse_of() (based on 5)
7) is requred DPCM on Renesas R-Car driver
8) is DT support on dummy driver

5) and 8) are main patch for DPCM on simple-card.

I'm still not 100% understand about DPCM, but 8) patch was needed
to DPCM FE/BE route, but is it wrong solution ?

About 5) patch,
I know Lars-Peter pointed DT idea for DPCM via
     http://lxr.free-electrons.com/source/Documentation/devicetree/bindings/media/video-interfaces.txt
My 5) patch used this idea, but, not 100%.
Because DPCM can use multi FE-BE connection (?)
So, it is just pointing BE endpoint via "remote".

	/* FrontEnd */
	simple-audio-card,dai-link@0 {

		remote = <&endpoint>;

		cpu { ...  };
		codec { ... };
	};

	/* BackEnd */
	endpoint: simple-audio-card,dai-link@1 {

		cpu { ... };
		codec { ... };
	};

We can list many DAI in future ?

	remote = <&endpoint0, &endpoint1, &endpoint2>;


Kuninori Morimoto (8):
  1) ASoC: simple-card: use asoc_simple_xxx prefix
  2) ASoC: simple-card: remove dai_link->cpu_dai_name when DT
  3) ASoC: simple-card: dai_link->init should be cared when multi DAI
  4) ASoC: simple-card: use common for_each_child_of_node() for loop
  5) ASoC: simple-card: add DPCM support when DT case
  6) ASoC: simple-card: remove is_top_level_node from asoc_simple_card_sub_parse_of()
  7) ASoC: rsnd: add dai_link stream name
  8) ASoC: add snd-soc-dummy DT support
