From: Vijendar Mukunda <Vijendar.Mukunda@amd.com>

On stream stop, currently CPU DAI stop sequence is invoked first
followed by DMA. For Few platforms, it is required to stop the
DMA first before stopping CPU DAI.

For Stoneyridge platform, it is required to invoke DMA driver stop
first rather than invoking DWC I2S controller stop.
Introduced new flag in sound card structure for reordering stop sequence.
Based on flag check, ASoC core will re-order the stop requence.

This feels like it should be a per dai_link option rather than a card
wide option - the system could have a mix of links that do and don't
want this depending on why it's an issue.  The name probably also wants
to be more specific to what's being reordered, something like
stop_dma_first for example since it's only for stops and moves the DMA
first.

As per our understanding by going with card wide option is easier rather
than checking dai link name for re-ordering the stop sequence for
specific platforms.
We will rename the flag as "stop_dma_fist" and will post the new version.

Why would we need to check the name for the link?  Presumably all
affected AMD cards would just unconditionally set the flag, and other
systems could do what they like?

This issue is only observed with older ACP2.x AMD platforms.
To make AMD specific platform change(which uses ACP 2.x IP), As per our
understanding we should only update the flag in ACP DMA driver by adding
flag in snd_pcm_substream structure rather than adding flag in card
structure.
Please suggest us, if there is any better place holder to add
"stop_dma_first" flag.

Due to some problem with mail client, i have received mail response
late. I have posted v2 version already.

Based on your suggestion, We will make the changes and post the new version.

I'd expect this to be configured by the machine driver in the dai_link.
It might need copying over to the substream for runtime use but the core
should do that.
