We've got quite a few bug reports showing the SOF driver being loaded
unintentionally recently, and the reason seems to be that users didn't
know the module option change: with the recent kernel, a new option
dsp_driver=1 has to be passed to a new module snd-intel-dspcfg
instead of snd_hda_intel.dmic_detect=0 option.
That is, actually there are two tricky things here:
- We changed the whole detection in another module and another
option semantics.
- The existing option for skipping the DSP probe was also renamed.
For avoiding the confusion and giving user more hint, this patch
reverts the renamed option dsp_driver back to dmic_detect for
snd-hda-intel module, and show the warning about the module option
change when the non-default value is passed.

Klaus Ethgen reported occasional high CPU usages in his system that
seem caused by HD-audio driver. The perf output revealed that it's
in the unsolicited event handling in the workqueue, and the problem
seems triggered by some communication stall between the controller and
the codec at the runtime or system resume.
Actually a similar phenomenon was seen in the past for other Intel
platforms, and we already applied the workaround to enforce sync-write
for CORB/RIRB verbs for Skylake and newer chipsets (commit
2756d9143a "ALSA: hda - Fix intermittent CORB/RIRB stall on Intel
chips"). Fortunately, the same workaround is applicable to the old
chipset, and the experiment showed the positive effect.
Based on the experiment result, this patch enables the sync-write
workaround for all Intel chipsets. The only reason I hesitated to
apply this workaround was about the possibly slightly higher CPU usage.
But if the lack of sync causes a much severer problem even for quite
old chip, we should think this would be necessary for all Intel chips.

The commit e38e486d66 ("ALSA: hda: Modify stream stripe mask only

clears the azx_dev->stripe flag at snd_hdac_stream_clear(), but this

Commit 5398e94fb7 ("ALSA: hda - Add DP-MST support for NVIDIA codecs")
introduced a slight change of behaviour how non-MST monitors are
assigned to PCMs on Intel platforms.
In the drm_audio_component.h interface, the third parameter
to pin_eld_notify() is pipe number. On Intel platforms, this value
is -1 for MST. On other platforms, a non-zero pipe id is used to
signal MST use.
This difference leads to some subtle differences in hdmi_find_pcm_slot()
with regards to how non-MST monitors are assigned to PCMs.
This patch restores the original behaviour on Intel platforms while
keeping the new allocation policy on other platforms.

We've added the bass speaker support on Acer 8951G by the commit
00066e9733 ("Add Acer Aspire Ethos 8951G model quirk"), but it seems
that the GPIO pin was wrongly set: while the commit turns off the bit
to power up the amp, the actual hardware reacts other way round,
i.e. GPIO bit on = amp on.
So this patch fixes the bug, turning on the GPIO bit 0x02 as default.
Since turning on the GPIO bit can be more easily managed with
alc_setup_gpio() call, we simplify the quirk code by integrating the
GPIO setup into the existing alc662_fixup_aspire_ethos_hp() and
dropping the whole ALC669_FIXUP_ACER_ASPIRE_ETHOS_SUBWOOFER quirk.

As a quick workaround, instead, this patch drops the binding in the

pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug
event handling, non-acomp codecs enable and register jack-detection
for every hdmi_spec_per_pin.
This patch updates every relevant function in hda_jack.h and its
implementation in hda_jack.c, to consider dev_id along with pin_nid.
Changes to the HD Audio specification to support DP-MST audio are
described in the Intel Document Change Notification (DCN) number
HDA040-A.
From HDA040-A, "For the case of multi stream capable Digital Display
Pin Widget, [the Get Pin Sense verb] can be used to read a specific
Device Entry state as reported in Get Device List Entry verb." This
patch updates the read_pin_sense() function to take the dev_id as an
argument and pass it as a parameter to the Get Pin Sense verb.
Bits 15 through 20 from the Unsolicited Response for intrinsic
events contain the index of the Device Entry that generated the
event. This patch updates the Unsolicited Response event handlers to
extract the device entry index from the response and pass it to
snd_hda_jack_tbl_get_from_tag().
This patch updates snd_hda_jack_tbl_new() to take a dev_id argument
and store it in the jack structure, and to make sure not to generate
a different tag when called more than once for the same nid.

Remove the workarounds added in commit fa763f1b28 ("ALSA:
hda - Force polling mode on CNL for fixing codec communication")
and commit a8d7bde23e ("ALSA: hda - Force polling mode on CFL
for fixing codec communication").
The workarounds are no longer needed after the more generic
change done in commit 2756d9143a ("ALSA: hda - Fix intermittent
CORB/RIRB stall on Intel chips"). This change applies to a larger
set of hardware and covers CFL and CNL as well.
Similar change was already done to SOF DSP HDA driver with
no regressions detected.

Semantics of port#0 differ between ICL and TGL:
ICL port#0 -> never used for HDAudio
ICL port#1 -> should be mapped to first pin (0x04)
TGL port#0 -> typically not used, but HW has the support,
so should be mapped to first pin (0x04)
TGL port#1 -> should be mapped to 2nd pin (0x06)
Refactor the port mapping logic to allow to take the above
differences into account. Fixes issues with HDAudio on some
TGL platforms.

Introduce a new flag in hdmi_spec to indicate the Intel platform-
specific fixups so that we can get rid of the lengthy codec ID
checks. The flag is set in intel_hsw_common_init() commonly.
