[alsa-devel] [PATCH v2 0/3] ASoC: topology: Add support for FE DAI & DAI links
From: Mengdong Lin mengdong.lin@linux.intel.com
This series allows topology to create FE DAI and DAI links from the PCM topology objects defined by the user space.
History: v2: Remove first 2 patches in v1 that were accepted. Add Ack by Takashi to patch 'ALSA: pcm: Add snd_pcm_rate_range_to_bits()' and add his comments on the function's assumption to c file.

The patch
ALSA: pcm: Add snd_pcm_rate_range_to_bits()
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

Topology will create FE DAIs dynamically from the PCM objects, and register them to the component.
A PCM topoplogy object describes a FE DAI and DAI link. Later patch will add FE DAI links as well.
Change tplg load ops for DAI: - Only process a DAI. - Pass the DAI driver pointer to the component driver for extra initialization.

I've sent out a patch to fix this: [PATCH] ASoC: topology: Fix setting of stream rates, rate_min and rate_max
Please review and overlook my v3 series which just merged this fix with the applied patches.

Yes, we can directly set the stream's rates, rate_min and rate_max from the topology caps. I revised this as you suggested in v3.
Sorry for the late reply. I'm just back from a two weeks CNY holiday.

Topology will also create FE DAI links dynamically from the PCM objects. These links will be removed when the component is removed and its topology info is unloaded.
The component driver can implement link_load/unload ops for extra intialization (e.g. error check) and destruction.

Mengdong, it might be easier to split this patch into 1/3 and 2,3/3 since 1/3 will be in Takashi's tree, but then that might not be needed it Takashi and Mark agree.

They'll need to all end up in one tree at some point since at least one of the ASoC patches depends on the ALSA core patch. Usually we do this by having me apply things (IIRC Takashi has already acked the ALSA patch).
