This series does not add new functionality but introduces a better
code partition to support machine drivers in Device Tree, as well as a
'componentization' of the PCM/topology parts needed for multi-client
support.

This cleanup was merged in the SOF tree and tested extensively with no
regressions identified. Thanks Ranjani and Daniel for combining your
proposals in a single change.

Changes since v1:
Rebased on top of Jaroslav's HDaudio changes (added in this series as
discussed with Mark)

Daniel Baluta (2):
  ASoC: SOF: Make creation of machine device from SOF core optional
  ASoC: SOF: Remove unused drv_name in sof_pdata

Jaroslav Kysela (3):
  ASoC: intel/skl/hda - export number of digital microphones via control
    components
  ASoC: Intel - use control components to describe card config
  ASoC: Intel - do not describe I/O configuration in the long card name

Ranjani Sridharan (8):
  ASoC: SOF: topology: remove snd_sof_init_topology()
  ASoC: SOF: core: modify the signature for snd_sof_create_page_table
  ASoC: SOF: core: move check for runtime callbacks to core
  ASoC: SOF: Introduce default_fw_filename member in sof_dev_desc
  ASoC: SOF: partition audio-related parts from SOF core
  ASoC: SOF: intel: hda: Modify signature for hda_codec_probe_bus()
  ASoC: SOF: remove nocodec_fw_filename
  ASoC: SOF: nocodec: Amend arguments for sof_nocodec_setup()

Use the control interface (field 'components' in the info structure)
to pass the I/O configuration details. The goal is to replace
the card long name with this.

The long card name might be used in GUI. This information should be hidden.

Add CONFIG_SND_SOC_INTEL_USER_FRIENDLY_LONG_NAMES configuration option.

Modify the signature for snd_sof_create_page_table to
take struct device pointer as an argument instead of
struct snd_sof_dev as this will be used by both the SOF
core device and its clients. Also, move the definition
out of core.c to utils.c.

For some platforms, the refcount is explicitly incremented
to prevent it from entering runtime suspend. This
should be be done during probe in the core instead
of being done in the PCM driver.

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

Currently the FW filename is obtained from the ACPI matching
table when determining which machine driver to use. In
preparation for making the machine driver ACPI match optional
for Device Tree platforms and moving the machine driver selection
out of the SOF core, this patch introduces the default_fw_filename
member in struct sof_dev_desc.

Once the machine driver selection is moved out of SOF core,
the nocodec_fw_filename will become obsolete and will be removed.

From: Pierre-Louis Bossart @ 2019-12-04 21:15 UTC (permalink / raw)
  To: alsa-devel; +Cc: tiwai, broonie, Ranjani Sridharan, Pierre-Louis Bossart

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

Move all the audio-specific code in the core,
audio-specific logic in the top-level PM callbacks
and the core header files into a separate file
(sof-audio.*) in preparation for adding an
audio client device.

In the process of moving all structure definitions
for widget, routes, pcm's etc, the snd_sof_dev
member in all these structs is replaced with
the snd_soc_component member. Also, use the component
device instead of the snd_sof_dev device wherever
possible in the PCM component driver,
control IO functions and the topology parser as the
component device will be moved over to the client
device later on.

From: Pierre-Louis Bossart @ 2019-12-04 21:15 UTC (permalink / raw)
  To: alsa-devel; +Cc: tiwai, broonie, Ranjani Sridharan, Pierre-Louis Bossart

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

The machine driver selection for HDA platforms will be
consolidated and moved out of the SOF DSP
probe callback. In preparation for that, modify the
signature for hda_codec_probe_bus() to pass the
hda_codec_use_common_hdmi as a variable while probing the
HDA codecs.

From: Daniel Baluta <daniel.baluta@nxp.com>

Currently, SOF probes machine drivers by creating a platform device
and passing the machine description as private data.

This is driven by the ACPI restrictions. Ideally, ACPI tables
should contain the description for the machine driver. This is
not possible because ACPI tables are frozen and used on multiple
OS-es (e.g Windows).

In the case of Device Tree we don't have this restriction, so we
choose to probe the machine drivers by creating a DT node as is
the standard ALSA way.

This patch makes the probing of machine drivers from SOF
core optional allowing for Device Tree platforms to decouple
the SOF core from machine driver probing.

Along with this, it also consolidates the machine driver selection
for Intel platforms by defining optional ops for selecting the machine
driver based on the ACPI match for HDA and non-HDA platforms and
setting the mach params.

Set the drv_name and tplg_filename for nocodec
machine driver in sof_machine_check().
This means the sof_nocodec_setup() does not
need the mach, plat_data or desc arguments any longer.

The patch

   ASoC: SOF: nocodec: Amend arguments for sof_nocodec_setup()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

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

The patch

   ASoC: SOF: Make creation of machine device from SOF core optional

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

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: SOF: Make creation of machine device from SOF core
 optional

Currently, SOF probes machine drivers by creating a platform device
and passing the machine description as private data.

This is driven by the ACPI restrictions. Ideally, ACPI tables
should contain the description for the machine driver. This is
not possible because ACPI tables are frozen and used on multiple
OS-es (e.g Windows).

In the case of Device Tree we don't have this restriction, so we
choose to probe the machine drivers by creating a DT node as is
the standard ALSA way.

This patch makes the probing of machine drivers from SOF
core optional allowing for Device Tree platforms to decouple
the SOF core from machine driver probing.

Along with this, it also consolidates the machine driver selection
for Intel platforms by defining optional ops for selecting the machine
driver based on the ACPI match for HDA and non-HDA platforms and
setting the mach params.

  To: Ranjani Sridharan; +Cc: tiwai, alsa-devel, Mark Brown, Pierre-Louis Bossart

The patch

   ASoC: SOF: intel: hda: Modify signature for hda_codec_probe_bus()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

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

Subject: [PATCH] ASoC: SOF: intel: hda: Modify signature for
 hda_codec_probe_bus()

The machine driver selection for HDA platforms will be
consolidated and moved out of the SOF DSP
probe callback. In preparation for that, modify the
signature for hda_codec_probe_bus() to pass the
hda_codec_use_common_hdmi as a variable while probing the
HDA codecs.

The patch

   ASoC: SOF: partition audio-related parts from SOF core

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

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: SOF: partition audio-related parts from SOF core

Move all the audio-specific code in the core,
audio-specific logic in the top-level PM callbacks
and the core header files into a separate file
(sof-audio.*) in preparation for adding an
audio client device.

In the process of moving all structure definitions
for widget, routes, pcm's etc, the snd_sof_dev
member in all these structs is replaced with
the snd_soc_component member. Also, use the component
device instead of the snd_sof_dev device wherever
possible in the PCM component driver,
control IO functions and the topology parser as the
component device will be moved over to the client
device later on.

The patch

   ASoC: SOF: Introduce default_fw_filename member in sof_dev_desc

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

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: SOF: Introduce default_fw_filename member in
 sof_dev_desc

Currently the FW filename is obtained from the ACPI matching
table when determining which machine driver to use. In
preparation for making the machine driver ACPI match optional
for Device Tree platforms and moving the machine driver selection
out of the SOF core, this patch introduces the default_fw_filename
member in struct sof_dev_desc.

Once the machine driver selection is moved out of SOF core,
the nocodec_fw_filename will become obsolete and will be removed.

The patch

   ASoC: SOF: core: move check for runtime callbacks to core

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

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: SOF: core: move check for runtime callbacks to core

For some platforms, the refcount is explicitly incremented
to prevent it from entering runtime suspend. This
should be be done during probe in the core instead
of being done in the PCM driver.

Subject: [PATCH] ASoC: SOF: core: modify the signature for
 snd_sof_create_page_table

Modify the signature for snd_sof_create_page_table to
take struct device pointer as an argument instead of
struct snd_sof_dev as this will be used by both the SOF
core device and its clients. Also, move the definition
out of core.c to utils.c.

The patch

   ASoC: Intel - do not describe I/O configuration in the long card name

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

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: Intel - do not describe I/O configuration in the long
 card name

The long card name might be used in GUI. This information should be hidden.

Add CONFIG_SND_SOC_INTEL_USER_FRIENDLY_LONG_NAMES configuration option.

Subject: [PATCH] ASoC: Intel - use control components to describe card config

Use the control interface (field 'components' in the info structure)
to pass the I/O configuration details. The goal is to replace
the card long name with this.
