PATCH 1/5 ASoC: Define soc_add_dai() to add a DAI to a component

From: Mengdong Lin <[email protected]>

Define soc_add_dai() as a wrapper to add a single DAI to a component. It can be reused to register a DAI dynamically by topology.

PATCH 2/5 ASoC: Support registering a DAI dynamically

In reply to [email protected]

From: Mengdong Lin <[email protected]>

Define API snd_soc_register_dai() to add a DAI dynamically and create the DAI widgets. Topology can use this API to register DAIs when probing a component with topology info. These DAIs's playback & capture widgets will be freed when the sound card is unregistered and the DAIs will be freed when cleaning up the component.

And a dobj is embedded into the struct snd_soc_dai_driver. Topology can use the dobj to find the DAI drivers created by it and free them when the topology component is removed.

PATCH 4/5 ASoC: topology: Add FE DAIs dynamically

In reply to [email protected]

From: Mengdong Lin <[email protected]>

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.

PATCH 5/5 ASoC: topology: Add FE DAI links dynamically

In reply to [email protected]

From: Mengdong Lin <[email protected]>

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.

Applied "ASoC: Support registering a DAI dynamically" to the asoc tree

In reply to [email protected]

The patch

ASoC: Support registering a DAI dynamically

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

This helper function can convert a given sample rate range to SNDRV_PCM_RATE_xxx bits.

Signed-off-by Mengdong Lin <[email protected]>

This function has an implicit assumption: the rates in the given range have only the pre-defined rates like 44100 or 16000.

In anyway, feel free to take my ack:

Applied "ASoC: topology: Add FE DAIs dynamically" to the asoc tree

In reply to [email protected]

The patch

ASoC: topology: Add FE DAIs dynamically

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

Subject: [PATCH] ASoC: topology: Add FE DAIs dynamically

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.

Subject: [PATCH] ASoC: topology: Add FE DAI links dynamically

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.
