ASoC: SOF: fix debugfs initialisation error handling
If debugfs initialisation fails partially in sof_probe_continue() some
debugfs files and the root directory might have been created
successfully. They have to be cleaned up if some of them failed too.

ASoC: SOF: Intel: hda: enable async suspend
The skylake driver disabled async suspend to prevent disabling
the DSP before the card was suspended during system suspend.
This code was carried over to the SOF driver. But, there is no
risk of the DSP getting disabled before the card is suspended
with the SOF driver. Therefore, it is safe to enable async suspend
and thereby optimize the system resume time.

ASoC: SOF: Intel: hda: turn off display power in resume
Turn off display power at the end of controller resume flow. This is now
possible with the changes done in commit 87fc20e4a0 ("ASoC: SOF:

is able to request the HDA link to be brought back up, the controller
no longer needs to blindly keep display power enabled.

08c2a4bc9f ALSA: hda: move Intel SoundWire ACPI scan to dedicated module
The ACPI scan capabilities is called from the intel-dspconfig as well
as the SOF/HDaudio drivers. This creates dependencies and randconfig issues
when HDaudio and SOF/SoundWire are not all configured as modules.

To simplify Kconfig dependencies between HDAudio, SoundWire, SOF and
intel-dspconfig, move the ACPI scan helpers to a dedicated
module. This follows the same idea as NHLT helpers which are already
handled as a dedicated module.

The only functional change is that the kernel parameter to filter
links is now handled by a different module, but that was only provided
for developers needing work-arounds for early BIOS releases.

8a49cd11e6 ASoC: SOF: ACPI: avoid reverse module dependency
The SOF-ACPI driver is backwards from the normal Linux model, it has a
generic driver that knows about all the specific drivers, as opposed to
having hardware specific drivers that link against a common framework.

This requires ugly Kconfig magic and leads to missed dependencies as
seen in this link error:

arm-linux-gnueabi-ld: sound/soc/sof/sof-pci-dev.o: in function `sof_acpi_probe':
sof-pci-dev.c:(.text+0x1c): undefined reference to `snd_intel_dsp_driver_probe'

Change it to use the normal probe order of starting with a specific
device in a driver, turning the sof-acpi-dev.c driver into a
library (exported symbols are name-spaced to avoid symbol pollution).

For backwards-compatibility with previous Kconfigs, the default values
for platform drivers uses the top-level ACPI configurations. The
modules were also renamed to allow for gradual transitions in test
scripts.

ASoC: SOF: relax ABI checks and avoid unnecessary warnings
With recent SOF 1.7 pre-releases, kernel has been emitting following
warnings at probe:

[10006.645216] sof-audio-pci 0000:00:1f.3: warn: FW ABI is more recent than kernel
[10006.652137] sof-audio-pci 0000:00:1f.3: warn: topology ABI is more recent than kernel

The warnings are emitted due to increase of the patch-level in firmware
mainline (to 3.17.1). But the patch level should not be considered even
in the strict ABI check, so modify the kernel side logic that makes the
check and only consider the major.minor components.

ASoC: SOF: fix runtime pm usage mismatch after probe errors
With current delayed probe implementation, sof_probe_complete is not
called in case of errors. And as this function is responsible for
decrementing runtime pm usage counter, this will result in following
problem:

 - probe driver in conditions where probe will fail (to force
   the condition on Intel SOF systems, set
   "snd_sof_intel_hda_common.codec_mask=0")
 - unload driver (runtime-pm usage_count is leaked)
 - fix the issue by installing missing fw, modifying module parameters,
   etc actions
 - try to load driver again -> success, probe ok
 -> device never enters runtime suspend

Fix the issue by storing result of delayed probe to a state variable and
providing new snd_sof_device_probe_completed() to be queried from SOF
PCI/ACPI/OF drivers.

If probe never completed successfully, runtime PM was not set up and
thus at remove(), we should not increment usage count anymore.

ASoC: SOF: Intel: detect DMIC number in SoundWire mixed config
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.

c99fafdfcc ASoC: SOF: Intel: hda: release display power at link_power
The i915 display power is requested both by controller (for init
and link reset) as well as by codec driver (for codec control).

There's an additional constraint that on some platforms frequent changes
to display power state may cause visible flicker. To avoid this, the SOF
hda controller requests display power whenever it is active and only
releases it when runtime suspended.

This patch utilizes the new hdac_bus link_power op to plug
into HDA link state changes. By monitoring link state changes,
we can keep the controller side display power wakeref until
the codec driver has completed its work, and only release
the wakeref when codec driver is suspended.

Opt-in to use snd_hdac_ext_bus_link_power() to manage HDA link
power up/down events.

This allows to reduce power consumption in cases where some HDA codecs
are suspended, but other child devices (HDA or non-HDA codecs) remain
active and controller itself remains in active state.

By using snd_hdac_ext_bus_link_power(), the individual HDA links can be
powered off and if all HDA codecs are powered down, the command DMA can
also be shut down.

The LKP bot reports the following issue:

WARNING: unmet direct dependencies detected for SOUNDWIRE_INTEL
  Depends on [m]: SOUNDWIRE [=m] && ACPI [=y] && SND_SOC [=y]
  Selected by [y]:
  - SND_SOC_SOF_INTEL_SOUNDWIRE [=y] && SOUND [=y] && !UML &&
  SND [=y] && SND_SOC [=y] && SND_SOC_SOF_TOPLEVEL [=y] &&
  SND_SOC_SOF_INTEL_TOPLEVEL [=y] && SND_SOC_SOF_INTEL_PCI [=y]

This comes from having tristates being configured independently, when
in practice the CONFIG_SOUNDWIRE needs to be aligned with the SOF
choices: when the SOF code is compiled as built-in, the
CONFIG_SOUNDWIRE also needs to be 'y'.

The easiest fix is to replace the 'depends' with a 'select' and have a
single user selection to activate SoundWire on Intel platforms. This
still allows regmap to be compiled independently as a module.

This is just a temporary fix, the select/depend usage will be
revisited and the SOF Kconfig re-organized, as suggested by Arnd
Bergman.

ASoC: SOF: Intel: fix page fault at probe if i915 init fails
The earlier commit to fix runtime PM in case i915 init fails,
introduces a possibility to hit a page fault.

snd_hdac_ext_bus_device_exit() is designed to be called from
dev.release(). Calling it outside device reference counting, is
not safe and may lead to calling the device_exit() function
twice. Additionally, as part of ext_bus_device_init(), the device
is also registered with snd_hdac_device_register(). Thus before
calling device_exit(), the device must be removed from device
hierarchy first.

Fix the issue by rolling back init actions by calling
hdac_device_unregister() and then releasing device with put_device().
This matches with existing code in hdac-ext module.

To complete the fix, add handling for the case where
hda_codec_load_module() returns -ENODEV, and clean up the hdac_ext
resources also in this case.

In future work, hdac-ext interface should be extended to allow clients
more flexibility to handle the life-cycle of individual devices, beyond
just the current snd_hdac_ext_bus_device_remove(), which removes all
devices.
