[PATCH 00/18] Clean ups and preparation for IPC abstraction in the SOF driver

[Ranjani Sridharan]

In preparation for adding support for the new IPC version that has been
introduced in the SOF firmware, this patch set includes some clean ups
and necessary modifications to commonly used functions that will be
re-used across different IPC-specific code.

[PATCH 02/18] ASoC: SOF: simplify snd_sof_device_remove()

[Ranjani Sridharan]

The commit "ASoC: SOF: core: Unregister machine driver before IPC and
debugfs" moved the call to unregister the machine driver to be done
before freeing the IPC. With this change, we can safely move the call to
snd_sof_remove() inside the same if() block just above.

[PATCH 03/18] ASoC: SOF: set swidget's core for scheduler widget

[Ranjani Sridharan]

Set the swidget's core for scheduler type widgets to match that of the
pipeline core. This simplifies the flow for core get/put during widget
setup/free.

[Ranjani Sridharan]

Modify the get_token op for string type tokens to pass the string as the
argument instead of a pointer to struct snd_soc_tplg_vendor_string_elem.

[PATCH 10/18] ASoC: SOF: change comp_dai to a pointer in struct snd_sof_dai

[Ranjani Sridharan]

This will avoid having to add the extended data for DAI components during
sof_widget_setup() as an extra step.

[PATCH 11/18] ASoC: SOF: make struct snd_sof_widget IPC agnostic

[Ranjani Sridharan]

Parse the UUID token and save it in the new uuid field in struct
snd_sof_widget. struct sof_ipc_comp_ext is no longer needed. So remove
it too.

ipc struct does not contain the uuid field.

[PATCH 13/18] ASoC: SOF: Add a tuples array to struct snd_sof_widget

[Ranjani Sridharan]

Add 2 new fields to snd_sof_widget to store an array of tuples
defined by struct snd_sof_tuple and the number of tuples. When the
topology gets parsed, the tuples associated with a widget will be stored
in this array and will be used to construct the IPC structure
depending on the IPC version.

[PATCH 14/18] ASoC: SOF: topology: Modify signature for token parsing functions

[Ranjani Sridharan]

Modify the signature for sof_parse_uuid_tokens(),
sof_parse_word_tokens() and sof_parse_string_tokens() to reorder the
arguments to be more intuitive and rename the count arg to num_tokens.

[PATCH 17/18] ASoC: SOF: make struct snd_sof_dai IPC agnostic

[Ranjani Sridharan]

Remove the comp_dai and dai_config members of struct snd_sof_dai and
replace it with a void *private field. Introduce a new struct
sof_dai_private_data that will contain the pointer to these two fields.
The topology parser will populate this structure and save it as part of
the "private" member in snd_sof_dai. Change all users of these fields to
use the private member instead.

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
