[PATCH 0/2] Adjust Stream Name and DT Bindings Updates

[Andrei Simion]

This patch set proposes the following changes to improve the flexibility
and configurability of the mchp-i2s-mcc driver by allowing the interface
name to be set through the device tree and by introducing a new property to
better manage multiple interfaces.

[PATCH 1/2] ASoC: atmel: mchp-i2s-mcc: Remove interface name from stream_name

[Andrei Simion]

From: Codrin Ciubotariu <codrin.ciubotariu@microchip.com>

Remove the interface name from the stream_name. The interface name (and the
index of the interface) can be set in DT using the sound-name-prefix string
property.

[PATCH 2/2] ASoC: dt-bindings: microchip,sama7g5-i2smcc: Add 'sound-name-prefix' property

[Andrei Simion]

From: Codrin Ciubotariu <codrin.ciubotariu@microchip.com>

Add 'sound-name-prefix' property to differentiate between interfaces in
DPCM use-cases. Property is optional.

This does not look correct. Name/prefix can be anything matching real
hardware, why are you restricting it? How can you predict all names?

You are duplicating property definitions. This is not needed at all.
Maybe your schema misses $ref to common schema.


Best regards,

I understand this does not differ per board, because it is component of
the SoC, yet still I do not see any value in enforcing name.

Yeah, the dai-common $ref is correct, so you should not need it. Do you
see any warning?

> or suggest any adjustments needed to align with the common schema?

I claim nothing has to be done and entire patch is redundant or not much
helpful. Your commit msg did not explain *why* this is needed and what
problem you are fixing, so what I can say? I don't know why should be
aligned because I do not understand the problem being fixed.

Krzysztof

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next

Thanks!

[1/2] ASoC: atmel: mchp-i2s-mcc: Remove interface name from stream_name
      commit: b09c71f3e8413ac0a9749f9d0d06f6f0d0b2cc65

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

One more point for future (I missed this before) - be sure you CC
necessary lists. Use get_maintainers or b4 for this. Skipping DT list
means skipping automation, so this would be a NAK anyway.
