[PATCH v3 00/16] ASoC: Add Rich Graph Card support

[Kuninori Morimoto]

Hi Mark

2 weeks have passed, and nothing happened.
Do I need to repost this patch-set ?

> Hi Mark
> 
> We already have Audio-Graph-Card which is Of-Graph base general sound
> card driver. Basically it supports basic CPU-Codec connection, and is
> also supporting DPCM connection. Because it was forcibly expanded to
> DPCM, DT parsing is very limited and very difficult to add new features
> on it, for example Multi-CPU/Codec support, Codec2Codec support, etc.
> 
> This patch adds more flexible new Rich-Graph-Card driver for it.
> Audio-Graph-Card and Rich-Graph-Card are similar, but don't have
> full compatibility.
> The reason why I need Rich-Graph-Card instead of updating Audio-Graph-Card
> is that it is very difficult to keep compatibility.
> 
> Rich-Graph-Card supports Normal/DPCM/Codec2Codec Connection wich
> Single/Multi DAIs. And it is possible to Customizing.
> 
> This patch-set adds Rich-Graph-Card driver and customized driver
> sample, and DT settings sample which can be used for testing.
> 
> To enable testing/debuging, this patch-set also adds Test-Component
> driver. We already have Dummy Component and/or Dummy DAI on soc-utils,
> but 1) we can't use it from DT, 2) it do nothing.
> Added new Test-Component can be used from DT, and it can indicate called
> function name. We can use it to trace callback order, understanding
> ALSA SoC behavior, etc, etc...
> Sample DT settings of Rich Graph Card is using Test-Component as CPU/Codec DAI.
> 
> You can easily try to use/test it if you added below line to your DT file.
> Your .config needs to have below CONFIGs to use/test it.
> It will probe sample Sound Card which has Normal/DPCM/Multi/Codec2Codec
> connections.

> Because Audio Graph Card2 is still under experimental stage, it will
> indicate such warning when probing, and the DT might be updated/exchanged.

> It can use Codec2Codec, but it will start automatically when probed,
> and can't stop it so far. It should be updated.

> v1 -> v2
> 	- don't use "port" base for_each loop
> 
> v2 -> v3
> 	- Rename audio-graph-card2 to rich-graph-card
> 	- Rename DSP to DPCM not to confuse
> 	- Normal/DPCM/Codec2Codec can use Single/Multi DAIs.
> 	- use dpcm/multi/codec2codec node instead of using extra compatible
> 	- Sample DTSI patch is separated to Single/Multi.
