From: Ajit Kumar Pandey <AjitKumar.Pandey@amd.com>
ACP DMA is used for loading SOF firmware into DSP memory and data
transfer from system memory to DSP memory. Add helper callbacks to
initialize and configure ACP DMA block for fw loading.

From: Ajit Kumar Pandey <AjitKumar.Pandey@amd.com>
ACP hw block configuration differs across various distributions
and hence it's required to register different drivers module for
distributions. For now we support three ACP drivers:
* ACP without SOF use case
* ACP with SOF use case
* ACP with SOF use case for DMIC and non SOF for I2S endpoints
As all above driver registers with common PCI ID for ACP hw block
we need code to determine ACP configuration and auto select driver
module. This patch expose function that return configuration flag
based on dmi checks for a system. ACP driver module probe register
platform device based on such configuration flag to avoid conflict
with other ACP drivers probed for same PCI ID.

Thanks for your patch, which is now commit f1bdd8d385a80356 ("ASoC:
amd: Add module to determine ACP configuration") in sound-asoc/for-next.

This definitely needs proper dependencies, to prevent asking the user
about this when configuring a kernel without AMD Audio ACP support.
I would have sent a patch, but...

These symbols are only used from sound/soc/sof/amd/pci-rn.c.
Why is this code living under sound/soc/amd/, while the ACP code
is under sound/soc/amd/acp/?

There's indeed a missing dependency that was fixed in
https://github.com/thesofproject/linux/pull/3284
Daniel, you may want to squash it in an update?
To Geert's point, there may be an additional need to add a
depends on SND_SOC_AMD_ACP
There are also a set of
SND_SOC_AMD_ACPyx options, not sure if any applies as a dependency here?

Or put them in an if block (IIRC I thought they were which was why the
dependency wasn't needed but I don't know what I was looking at if I did
check that).

There will be some delays in handling this as I'm in vacation until next Monday.

Probably you were looking at sound/soc/amd/acp/Kconfig, where all the
other ACP options live, and where you had applied my earlier patch
to wrap everything in a big "if".

Add PCI driver module to enable sof pci device support for Renoir.
If machine flag set to FLAG_SOF_ONLY_DMIC this pci driver register
platform device for non dsp based I2S platform device. If machine
flag is not enabled for SOF pci probe will return without invoking
sof device probe and registration

We have moved legacy based machine struct into platform driver to
resolve module dependency with non-SOF ALSA build, hence removed
it from acp-config driver module.

Add new sof dais and config to pass topology file configuration
to SOF firmware running on ACP's DSP core. ACP firmware support
I2S_BT, I2S_SP and DMIC controller hence add three new dais to
the list of supported sof_dais

Add callback to notify PSP after loading firmware on DSP. PSP will
validate the loaded firmware and set qualifier bit to run firmware
on secured AMD systems.

From: YC Hung <yc.hung@mediatek.com>
This patch initialize to support SOF on Mediatek mt8195 platform.
MT8195 has four Cortex A78 cores paired with four Cortex A55 cores.
It also has Cadence HiFi-4 DSP single core. There are shared DRAM and
mailbox interrupt between AP and DSP to use for IPC communication.

Please send a fix for this on top of topic/sof-dev. I will take care of

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
