First six of the backport address numerous problems troubling HDAudio configuration users for Skylake driver. Upstream series: "ASoC: Intel: Skylake: Fix HDaudio and Dmic" [1] provides the explanation and reasoning behind it. These have been initialy pushed into v5.7-rc1 via: "sound updates for 5.7-rc1" [2] by Takashi.
Last two patches are from: "Add support for different DMIC configurations" [3] which focuses on HDAudio with DMIC configuration. Patch: "ASoC: Intel: Skylake: Add alternative topology binary name" of the mentioned series has already been merged to v5.4.y -stable and thus it's not included here.
Fixes target mainly Skylake and Kabylake based platforms, released in 2015-2016 period.

commit 2ef81057d80456870b97890dd79c8f56a85b1242 upstream.
Skylake driver does the controller init operation twice: - first during probe (only to stop it just before scheduling probe_work) - and during said probe_work where the actual correct sequence is executed
To properly complete boot sequence when iDisp codec is present, bus initialization has to be called only after _i915_init() finishes. With additional _reset_list preceding _i915_init(), iDisp codec never gets the chance to enumerate on the link. Remove the superfluous initialization to address the issue.

With _reset_link removed from the probe sequence, codec_mask at the time skl_find_hda_machine() is invoked will always be 0, so hda machine will never be chosen. Rather than reorganizing boot flow, be permissive about invalid mask. codec_mask will be set to proper value during probe_work - before skl_codec_create() ever gets called.

Some configurations expose no NHLT table at all within their /sys/firmware/acpi/tables. To prevent NULL-dereference errors from occurring, adjust probe flow and append additional safety checks in functions involved in NHLT lifecycle.

Due to unconditional initial timeouts, firmware may fail to load during its initialization. This issue cannot be resolved on driver side as it is caused by external sources such as CSME but has to be accounted for nonetheless.

commit 7693cadac86548b30389a6e11d78c38db654f393 upstream.
Each purge request is sent by driver after master core is powered up and unresetted but before it is unstalled. On unstall, ROM begins processing the request and initializing environment for FW load. Host should await ROM's ack before moving forward. Without doing so, ROM init poll may start too early and false timeouts can occur.

For pipes supporting multiple input/output formats, kcontrol is created and selection of pipe input and output configuration is done based on control set.
If more than one configuration is supported, then this patch allows user to select configuration of choice using amixer settings.

commit 2d744ecf2b98405723a2138a547e5c75009bc4e5 upstream.
Automatically choose DMIC pipeline format configuration depending on information included in NHLT. Change the access rights of appropriate kcontrols to read-only in order to prevent user interference.

First six of the backport address numerous problems troubling HDAudio configuration users for Skylake driver. Upstream series: "ASoC: Intel: Skylake: Fix HDaudio and Dmic" [1] provides the explanation and reasoning behind it. These have been initialy pushed into v5.7-rc1 via: "sound updates for 5.7-rc1" [2] by Takashi.
Last two patches are from: "Add support for different DMIC configurations" [3] which focuses on HDAudio with DMIC configuration. Patch: "ASoC: Intel: Skylake: Add alternative topology binary name" of the mentioned series has already been merged to v5.4.y -stable and thus it's not included here.
Fixes target mainly Skylake and Kabylake based platforms, released in 2015-2016 period.
Thanks for these, it was very easy to pick them up in this format, much appreciated.
