So what is the point of this compatible? There is no user of it and I
think you added QCS8275 for this case exactly...

Shall I start reverting commits from Qualcomm because you post patches
"just in case" and turns out they are completely not needed? No single
user of such code?

Krzysztof

@Mark,

In case it wasn't obvious, please do not merge the patch till we get
some clarification. For sure it is wrong one way or another: either
incomplete or just duplicated.

The device tree currently uses qcs8275 as the sound compatible, and
the corresponding Device tree changes have already been applied and merged.

Reverting this now would break the ABI.

A new device tree patch with qcs8300 is currently under review:

https://lore.kernel.org/linux-arm-msm/20250910044512.1369640-1-mohammad.rafi.shaik@oss.qualcomm.com/

Once the machine driver and device tree patch with qcs8300 are accepted 
and merged,

I will promptly submit a cleanup patch to remove of discontinued 
compatibles from the machine driver.

If the above explanation is acceptable, please help with approvals.

I will submit the cleanup patch to remove discontinued compatibles,once 
the qcs8300 support added in driver and device tree considering ABI 
should not break.

If reverting would break ABI then:

This is ABI break thus NAK.

So this is the same hardware? Then no, we do not rename compatibles.

The QCS8275 compatible snuck in before we concluded the pathway of
renaming the SoC to reflect its actual name..

In this case, I think we'll just have to eat the cost and go with the
existing compatible, because it's simply cosmetic.

That said.. I'm a little confused why we're accepting SoC-compatibles
as well as board-compatibles for soundcards (e.g. rb2, rb3gen2,
6940idp) in parallel.. is it with an intention that the SoC one is
present in reference designs and therefore will be common?

Agree, the existing compatible is discontinued naming convention,
will remove existing qcs8275 and go with qcs8300.

"Sound card" here is partially a software or architectural construct.
Basically bindings for the sound machine driver. There is no such thing
as sound card on the device, there is bunch of audio-related components.

That's why we assume that many boards of given SoC will use same sound
card driver. Some boards might be also different so they have their own
compatible... or they were added in different time.

I don't have particular guidelines here, for me it is a bit blurry.

Krzysztof

That would be a rename, so again "no, we do not rename compatibles".

You are stuck with qcs8275.

ACK,

will drop the Renaming compatible string change.

Instead of renaming the compatible string, will go with the existing 
compatible and fix the driver match data by updating the driver name. 
This approach allows us to continue using the same compatible as 
"qcs8275-sndcard".

will update the driver match data name to QCS8300 to load the correct 
sound topology and ALSA UCM configuration files, which are added under 
the actual SoC QCS8300 directory in linux-firmware.

Thanks & regards,
Rafi.
