[PATCH v2 00/11] ASoC: SOF/Intel/SoundWire: add missing quirks and DMIC support
HP Spectre x360 convertible devices rely on a mixed SoundWire+DMIC configuration which wasn't well supported. This lead to the discovery that we missed the TGL_HDMI quirk on a number of Dell devices, the addition of DMIC autodetection (based on NHLT tables), the addition of new component strings needed by UCM, and work-arounds due to problematic DSDT tables.
Changes since v1: Rebase to remove first three patches already merged. Fix allmodconfig issues (undeclared kernel parameter)
Bard Liao (1): ASoC: intel: sof_sdw: add trace for dai links
Guennadi Liakhovetski (1): ASoC: SOF: Intel: HDA: don't keep a temporary variable

The quirk table is a mess, let's reorganize it by generation before making sure that the quirks are consistent for each generation.

UCM needs to know which microphone is used (dmic or RT715-based), let's add the information in the component string.
Note the slight change from HDAudio platforms where 'cfg-dmics' was used. 'cfg-mics' is used here with the intent that this component string describes either the number of PCH-attached microphones or the number of RT715-attached ones (the assumption is that the two configurations are mutually exclusive).

Current driver create DMIC dai based on quirk for each platforms, so we need to add quirk for new platforms. Now driver reports DMIC number to machine driver and machine driver can create DMIC dai based on this information. The old check is reserved for some platforms may be failed to set the DMIC number in BIOS.

We have existing platforms where the wrong machine is selected. We need to make sure the number of devices reported on a link matches what we expect for a link descriptor. This helps avoid using the TGL-RVP configuration for an HP platform or vice-versa, depending on the order in which they are inserted in the table.

The pinmux allows for 2 SoundWire links to be enabled along with DMICs. This was the default configuration on the TGL-RVP.
One issue with this configuration is that we don't have a means to automatically detect how many DMICs are used, which in turn requires the user to manually rename the topology file required on a platform.
This was borderline acceptable for Intel RVPs, but now that this configuration is present in HP devices we need to automate the process.
This patch makes use of the NHLT information and will pass the DMIC number to the machine driver as a parameter. A follow-up patch will expose the DMIC number to userspace/UCM with the configuration strings.
The Google devices do make use of DMICs instead of SoundWire link 2 and 3, but their topology is unique enough that they do not need any NHTL support or topology renaming.

fixup_tplg_name() doesn't need to keep the string, allocated for filename - it's temporary.

It's useful for debug and system integration to show cases where we ignore the number of microphones reported by NHLT.

HP Spectre x360 convertible devices rely on a mixed SoundWire+DMIC configuration which wasn't well supported. This lead to the discovery that we missed the TGL_HDMI quirk on a number of Dell devices, the addition of DMIC autodetection (based on NHLT tables), the addition of new component strings needed by UCM, and work-arounds due to problematic DSDT tables.

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
