[alsa-devel] [PATCH 0/6 v4] Add ASoC support for AMD Stoney APUs
This patch set updates the AMD GPU and Audio CoProcessor (ACP) audio drivers and the designware i2s driver for Stoney (ST). ST is an APU similar to Carrizo (CZ) which already has ACP audio support. The i2s controller and ACP audio DMA engine are part of the GPU and both need updating so I would like to upstream the whole patch set via one tree if possible.
The entire patch set can be viewed here: https://cgit.freedesktop.org/~agd5f/linux/log/?h=stoney_acp3
I just need acks from audio on the remaining patches that touch audio (1, 5, 6), and then I can send a pull request.
Thanks!
Alex
v2: - Patch 1 is already applied to the audio tree, just including it for completeness since it's required for this patch set and it's not yet in the drm tree. - New patch to share asic types between gpu and audio drivers - ACPI ID changed for rt5650 machine driver - Integrate feedback on other patches
v3: - resend remaining patches that have not been applied yet
v4: - Integrate feedback from v3 - Add Mark's acks from v3 - Integrate a machine driver fix from Dylan Reid

Amdgpu asic types will be required for other drivers too. Hence, its better to keep it in a separate include file.

Added DMA driver changes for Stoney platform. Below are the key differences between Stoney and CZ
In Stoney, Memory Gating is disabled.SRAM Banks won't be turned off.No Of SRAM Banks reduced to 6. DAGB Garlic Interface used and 16 bit resolution is supported. SRAM bank 1 & SRAM bank 2 will be used for playback scenario. SRAM Bank 3 & SRAM Bank 4 will be used for Capture scenario.

The patch
ASoC: AMD: Audio buffer related changes for Stoney
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

From: Vijendar Mukunda Vijendar.Mukunda@amd.com Date: Wed, 13 Sep 2017 13:57:54 -0400 Subject: [PATCH] ASoC: AMD: Audio buffer related changes for Stoney
Stoney uses 16kb SRAM memory for playback and 16Kb for capture.Modified Max buffer size to have the correct mapping between System Memory and SRAM.
Added snd_pcm_hardware structures for playback and capture for Stoney.

No, send me a pull request for the dependencies so we can do a cross merge. I want to make sure that when this gets reviewed it actually gets merged.

I'm not quite sure what you mean by the cross merge. There are no dependencies outside this patch set. The only patches that touch drm are patches 1 and 2. Patch 1 touches both audio and drm, patch 2 just touches drm. Do you want me to send you a pull request for patches 1 and 2 and then would you'd send Dave a pull request for the audio side (patches 3-6)?

I can't see any reason for patch 1 to be a single patch, just have a DRM patch that adds the property and then a separate audio patch that uses it. Send me a pull request for that and patch 2 then I can handle the audio stuff.

I guess, but I thought you were a maintainer for this stuff and could merge things yourself?

Sorry travelling last week and swamped this week. I'm going to try and get it done tomorrow, otherwise, probably the week after.

No worries, it's only -rc3 so we've got 3-4 weeks.
