ASoC: Intel: acpi-match: split CNL tables in three

Due to firmware manifest/signature differences, we have to use
different firmware names, so split CNL machine table in three (CNL,
CFL, CML).

The CFL table is currently empty since all known platforms use

ASoC: rt5677: Disable irq at suspend

The irq is disabled at suspend to avoid running the threaded irq
handler after the codec has been powered off. At resume, codec irq is
re-enabled and the interrupt status register is checked to see if
headphone has been pluggnd/unplugged while the device is suspended.

There is still a chance that the headphone gets enabled or disabled
after the codec is suspended. disable_irq syncs the threaded irq
handler, but soc-jack's threaded irq handler schedules a delayed
work to poll gpios (for debounce). This is still OK. The codec won't
be powered back on again because all audio paths have been suspended,
and there are no force enabled supply widgets (MICBIAS1 is disabled).
The gpio status read after codec power off could be wrong, so the
gpio values are checked again after resume.

The codec dies when RT5677_PWR_ANLG2(MX-64h) is set to 0xACE1
while it's streaming audio over SPI. The DSP firmware turns
on PLL2 (MX-64 bit 8) when SPI streaming starts.  However regmap
does not believe that register can change by itself. When
BST1 (bit 15) is turned on with regmap_update_bits(), it doesn't

ALSA SoC has 2 functions.
snd_soc_register_dai()  is used from topology
snd_soc_register_dais() is used from snd_soc_add_component()

In general, people think like _dai() is called from _dais()
with for loop. But in reality, these are very similar
but different implementation.
We shouldn't have duplicated and confusing implementation.

snd_soc_register_dai() is now used from topology.
But to reduce duplicated code, it should be used from _dais(), too.
To prepare it, this patch adds missing parameter legacy_dai_naming
to snd_soc_register_dai().

ASoC: pcm: update FE/BE trigger order based on the command

Currently, the trigger orders SND_SOC_DPCM_TRIGGER_PRE/POST
determine the order in which FE DAI and BE DAI are triggered.
In the case of SND_SOC_DPCM_TRIGGER_PRE, the FE DAI is
triggered before the BE DAI and in the case of
SND_SOC_DPCM_TRIGGER_POST, the BE DAI is triggered before
the FE DAI. And this order remains the same irrespective of the
trigger command.

In the case of the SOF driver, during playback, the FW
expects the BE DAI to be triggered before the FE DAI during
the START trigger. The BE DAI trigger handles the starting of
Link DMA and so it must be started before the FE DAI is started
to prevent xruns during pause/release. This can be addressed
by setting the trigger order for the FE dai link to
SND_SOC_DPCM_TRIGGER_POST. But during the STOP trigger,
the FW expects the FE DAI to be triggered before the BE DAI.
Retaining the same order during the START and STOP commands,
results in FW error as the DAI component in the FW is still
active.

The issue can be fixed by mirroring the trigger order of
FE and BE DAI's during the START and STOP trigger. So, with the
trigger order set to SND_SOC_DPCM_TRIGGER_PRE, the FE DAI will be
trigger first during SNDRV_PCM_TRIGGER_START/STOP/RESUME
and the BE DAI will be triggered first during the
STOP/SUSPEND/PAUSE commands. Conversely, with the trigger order
set to SND_SOC_DPCM_TRIGGER_POST, the BE DAI will be triggered
first during the SNDRV_PCM_TRIGGER_START/STOP/RESUME commands
and the FE DAI will be triggered first during the
SNDRV_PCM_TRIGGER_STOP/SUSPEND/PAUSE commands.

ASoC: SOF: Intel: use def_tristate, avoid using select

So far we used select to use the relevant built-in/module options, but
this led to blurring layers between core and Intel Kconfigs.

Use def_tristate works just as well and removes Intel stuff from the code.

turn referenced by the sof-of-dev driver. This creates a reverse

ALSA: hda/hdmi - implement mst_no_extra_pcms flag

To support the DP-MST multiple streams via single connector feature,
the HDMI driver was extended with the concept of backup PCMs. See
commit 9152085defb6 ("ALSA: hda - add DP MST audio support").

This implementation works fine with snd_hda_intel.c as PCM topology
is fully managed within the single driver.

When the HDA codec driver is used from ASoC components, the concept
of backup PCMs no longer fits. For ASoC topologies, the physical
HDMI converters are presented as backend DAIs and these should match
with hardware capabilities. The ASoC topology may define arbitrary
PCMs (i.e. frontend DAIs) and have processing elements before eventual
routing to the HDMI BE DAIs. With backup PCMs, the link between
FE and BE DAIs would become dynamic and change when monitors are
(un)plugged. This would lead to modifying the topology every time
hotplug events happen, which is not currently possible in ASoC and
there does not seem to be any obvious benefits from this design.

To overcome above problems and enable the HDMI driver to be used
from ASoC, this patch adds a new mode (mst_no_extra_pcms flags) to
patch_hdmi.c. In this mode, the codec driver does not assume
the backup PCMs to be created.

drm: bridge: dw-hdmi: Report connector status using callback

Allow codec driver register callback function for plug event.

The callback registration flow:
dw-hdmi <--- hw-hdmi-i2s-audio <--- hdmi-codec

dw-hdmi-i2s-audio implements hook_plugged_cb op
so codec driver can register the callback.

dw-hdmi exports a function dw_hdmi_set_plugged_cb so platform device
can register the callback.

When connector plug/unplug event happens, report this event using the
callback.

Make sure that audio and drm are using the single source of truth for
connector status.

ASoC: SOF: PM: Add support for DSP D0i3 state when entering S0ix

When system is entering into S0ix, the PCI device may transition to the
D0i3 substate instead of D3. In D0i3, some always-on functionality can
be enabled, such as acoustic event detection, voice activity detection
or hotwording. When an event is detected, the DSP firmware can wake-up
the device for a transition to D0 with an interrupt.

ASoC: SOF: ignore suspend/resume for D0ix compatible streams

During system suspend, the PM framework will freeze all applications and
the ALSA/ASoC core will suspend all RUNNING PCM streams.

However, D0ix-compatible PCM streams should keep the related pipelines
active in the DSP when the system is entering S0ix. The TRIGGER_SUSPEND
event is trapped in such cases to prevent the pipelines from being
stopped. Likewise, the TRIGGER_RESUME/START events should not affect the
pipeline state.

The SOF driver also triggers some DSP Firmware pipelines based on the
DAPM widgets power events. In such cases, we also ignore PRE_PMU and
POST_PMD events to keep the pipelines active.
