[PATCH 0/7] ALSA/ASoC: Intel: add I2S function topology support

[Bard Liao]

Currently, function topology is only used by the SoundWire machines.
Extend the support to the I2S machines.

The only ALSA change is to lower the log level. Let's go through the
ASoC tree.

Bard Liao (7):
  ASoC: SOF: get nhlt from all topologies
  ALSA: intel-nhlt: lower intel_nhlt_ssp_device_type log level
  ASoC: Intel: sof-function-topology-lib: create common helpers
  ASoC: Intel: sof-function-topology-lib: skip non-exist file in
    best_effort mode
  ASoC: Intel: sof-function-topology-lib: add I2S support for
    sof_sdw_get_tplg_files
  ASoC: Intel: sof-function-topology-lib: add get_function_topology for
    I2S machines
  ASoC: soc-acpi-intel-ptl-match: I2S machines: use function topology

[PATCH 1/7] ASoC: SOF: get nhlt from all topologies

[Bard Liao]

The existing code assumes there is only one NHLT blob either from BIOS
or topology. As function topologies are used and each function topology
contains a NHLT blob section, we need to search the matching NHLT blob
from all the NHLT blobs.
The commit suggests adding a list of NHLTs and search the NHLTs from the
list.

[PATCH 2/7] ALSA: intel-nhlt: lower intel_nhlt_ssp_device_type log level

[Bard Liao]

To support multiple topology fragments per function, this function
could be called multiple types with different NHLT blobs from different
fragments. Downgrade the error message to debug level since the SSP
device type could be found from one of the nhlt.

[PATCH 4/7] ASoC: Intel: sof-function-topology-lib: skip non-exist file in best_effort mode

[Bard Liao]

Currently we will fallback to the monolithic topology if any function
topology is missing. But the monolithic topology may not exist if
best_effort is set. We should load the existing function topologies in
the case.

The DAI link 0 of sof_ssp_amp.c is HDMI and the amp DAI link id is 2.

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
