Note:
- The machine driver patch is made by the collaboration of
  Cheng-Yi Chiang <cychiang@chromium.org>
  Rohit kumar <rohitkr@codeaurora.org>
  Ajit Pandey <ajitp@codeaurora.org>
  But Ajit has left codeaurora.
- This patch series needs HDMI DAI name SC7180_LPASS_DP defined in sc7180-lpass.h.
  It will be posted in the newer patchset of https://patchwork.kernel.org/patch/11745565/

Changes from v1 to v2:
- Ducumentation: Addressed all suggestions from Doug.
- Machine driver:
  - Fix comment style for license.
  - Sort includes.
  - Remove sc7180_snd_hw_params.
  - Remove sc7180_dai_init and use aux device instead for headset jack registration.
  - Statically define format for Primary MI2S.
  - Atomic is not a concern because there is mutex in card to make sure
    startup and shutdown happen sequentially.
  - Fix missing return -EINVAL in startup.
  - Use static sound card.
  - Use devm_kzalloc to avoid kfree.

Changes from v2 to v3:
- Ducumentation: Addressed suggestions from Srini.
- Machine driver:
  - Reuse qcom_snd_parse_of to parse properties.
  - Remove playback-only and capture-only.
  - Misc fixes to address comments.

Changes from v3 to v4:
- Ducumentation: Addressed suggestions from Rob.
 - Remove definition of dai.
 - Use 'sound-dai: true' for sound-dai schema.
 - Add reg property to pass 'make dt_binding_check' check although reg is not used in the driver.
- Machine driver:
 - Add Reviewed-by: Tzung-Bi Shih <tzungbi@google.com>

Changes from v4 to v5:
- Documentation: Addressed suggestions from Rob.
 - Add definition for "#address-cells" and "#size-cells".
 - Add additionalProperties: false
 - Add required properties.

Changes from v5 to v6:
- Documentation: Addressed suggestions from Rob.
 - Drop contains in compatible strings.
 - Only allow dai-link@[0-9]
 - Remove reg ref since it has a type definition already.

Changes from v6 to v7
- Documentation:
  - Add headset-jack and hdmi-jack to specify the codec
    responsible for jack detection.
- HDMI codec driver:
  - Use component set_jack ops instead of exporting hdmi_codec_set_jack_detect.
- Machine driver:
  - Removed aux device following Stephan's suggestion.
  - Use headset-jack and hdmi-jack to specify the codec
    responsible for jack detection.
  - Add support for HDMI(actually DP) playback.

Changes from v7 to v8
- Documentation:
  - Remove headset-jack and hdmi-jack.
- Machine driver:
  - Let machine driver decide whether there is a jack on the DAI.

Changes from v8 to v9
- hdmi-codec driver:
  - Fixed the naming.
- Machine driver:
  - Fixed unused fields.
  - Moved snd_soc_card_set_drvdata
  - Keep the naming of HDMI as dai name until v5 of lpass-hdmi patches.

Changes from v9 to v10
- Documentation:
  - Let compatible string be more specific for board configuration to allow
    for future changes.
- Machine driver:
  - Fixed unused include and macro.
  - Add temporary macro SC7180_LPASS_DP for future change in sc7180-lpass.h.
  - Let sound card be dynamically allocated.
  - Change compatible string accordingly.

Changes from v10 to v11
- Machine driver:
  - Use temporary macro LPASS_DP_RX for future change in sc7180-lpass.h.

Use set_jack ops to set jack so machine drivers do not need to include
hdmi-codec.h explicitly.

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.

Hi Rob,
There was a change between v9 and v10 on compatible string so I did
not add your Reviewed-by.
Now it is "qcom,sc7180-sndcard-rt5682-m98357-1mic" following Stephan's
comment in

https://patchwork.kernel.org/comment/23608881/

to make compatible string more specific to board configuration.
I only add the note to the cover letter. Sorry the cover letter became
too long to follow.
I will add the note in patch mail itself for future changes.
Thanks for taking a look again.

Hi Rob,
Could you please kindly review this patch ?

v11 contains the compatible string  "qcom,sc7180-sndcard-rt5682-m98357-1mic"
following Stephan's suggestion in

"[v9,3/3] ASoC: qcom: sc7180: Add machine driver for sound card registration"
( https://patchwork.kernel.org/patch/11770201/#23608881 )

to specify the combination of components.

Please let me know if this looks good to you.
Thanks!

Hi Srini and Stephan,
May I get your Reviewed-By for this patch ?
There are some patches on the machine driver for different
configurations pending on this one so I would hope to get this one
merged first.

Thanks a lot for reviewing it!

Hi Cheng,

Sorry for such late review w.r.t compatibles,

This information can come from the dai link description itself, why 
should compatible string have this information?

Can't we have better compatible string with actual board name or use the 
same compatible name as used by other boards?

Can you give us some details on the advantages of doing this way?

Or am I missing something?

AFAIU, you should add proper board name / model name to the compatible 
string rather than describe how its connected. Connection is already 
part of dai link definition.

On the other hand model property can include variant information.
This can also be used to set card long name which will help in UCM2.

The reason I had to bring this up is because the use-space (ucm in this 
case) will not be in a position to differentiate between different board 
variants to select correct mixer controls, so its going to be a pain!


Thanks,
srini

I think dailink description is not enough to specify everything
machine driver needs to know.
E.g. there is a variation where there are front mic and rear mic. We
need to tell the machine driver about it so
it can create proper widget, route, and controls.
The codec combination also matters. There will be a variation where
rt5682 is replaced with adau7002 for dmic.
Although machine driver can derive some information by looking at dailink,
I think specifying it explicitly in the compatible string is easier to
tell what machine driver should do, e.g.
setting PLL related to rt5682 or not.

Machine driver can easily tell what is expected when it sees the
compatible string (or model property, as you suggested below).
E.g. in 1-mic v.s. 2-mic case, the patch by Ajye Huang:

"[v1,2/2] ASoC: qcom: sc7180: Modify machine driver for 2mic"

You can see widget, route, controls are used according to the configuration.
The alternative approach is to check whether "dmic-gpio" property
exists to decide adding these stuff or not.
But it makes the intent less easier to understand.

I think your suggestions makes sense since we need to consider UCM.
Having the card with the same name doing different things will be
confusing to user (and to UCM).
I'll follow your suggestion to use the same compatible string, and put
the board variation information in card name using model property.
Thanks a lot for the great help!

Thanks Srini for the suggestion in the review of compatible strings.
In the next version (v12), I will modify accordingly to use model
property rather than compatible string to specify board configuration.
Thanks!

That sounds like something that could be better described with
properties (including for example the existing bindings used for setting
up things like analogue outputs and DAPM routes)?

These feel more like things that fit with compatible, though please take
a look at Morimoto-san's (CCed) work on generic sound cards for more
complex devices:

   https://lore.kernel.org/alsa-devel/87imbeybq5.wl-kuninori.morimoto.gx@renesas.com/

This is not yet implemented but it'd be good to make sure that the
Qualcomm systems can be handled too in future.

OTOH if you have lots of compatibles then it can get hard to work out
exactly which one corresponds to a given board.
