ASoC: Intel: Skylake: Fix driver hang during shutdown
AudioDSP cores and HDAudio links need to be turned off on shutdown to
ensure no communication or data transfer occurs during the procedure.

ASoC: Intel: Skylake: fix possible memory leak in skl_codec_device_init()
If snd_hdac_device_register() fails, 'codec' and name allocated in
dev_set_name() called in snd_hdac_device_init() are leaked. Fix this
by calling put_device(), so they can be freed in snd_hda_codec_dev_release()
and kobject_cleanup().

ASoC: Intel: Skylake: simplify S3 resume flows
Commit cce6c149eb ("ASoC: Intel: Skylake: add link management")
added a perfectly logical/symmetrical link handling for
'suspend_active' aka S0ix

However that commit also added a less obvious part, where during S3
resume the code will "turn off the links which are off before suspend"
as well as stop the cmd_io which is not started.

This sequence looks completely unnecessary and possibly wrong, remove it.

3fd63658ca ASoC: Intel: Drop hdac_ext usage for codec device creation
To make snd_hda_codec_device_init() the only constructor for struct
hda_codec instances remaining tasks are:

1) no struct may wrap struct hda_codec as its base type
2) bus drivers (skylake and sof) which are the current hdac_ext users
   need to be adjusted to make use of newly added codec init and exit
   routines instead
3) as bus drivers (skylake and sof) are to be responsible for creating
   codec device and assigning it to hdac_hda_priv->codec,
   hdac_hda_dev_probe() has to be freed of that job

To keep git bisect happy, all of these in made in one-go.

ASoC: hdac: make SOF HDA codec driver probe deterministic
To provide backward compatibility to older systems, the SOF HDA driver
allows user to specify which HDMI codec driver to use at runtime via
kernel parameter. This mechanism has a subtle flaw in that it assumes
the codec drivers not to be loaded when the SOF PCI driver is loaded.

The problem is rooted in use of the hdev->type field.
snd_hdac_ext_bus_device_init() initializes this field to HDA_DEV_ASOC.
This signals the HDA core that ASoC drivers should be considered in
driver matching (hda_bus_match()). The SOF and SST drivers continue by
overriding this field to HDA_DEV_LEGACY and proceeding to load driver
modules with request_module(). Correct drivers will get loaded and
attached.

If however the codec drivers are already loaded when
snd_hdac_ext_bus_device_init() is called, the matching will not work as
expected as device type is still set to HDA_DEV_ASOC. Specifically if
hdac-hdmi is attached when machine driver is configured to use hdac-hda,
this leads to out-of-bounds memory access in
hda_dsp_hdmi_build_controls().

Fix the issue by adding codec type as a parameter to
snd_hdac_ext_bus_device_init() and ensuring type is set correctly from
the start.

82d9d54a6c ALSA: hda: add Intel DSP configuration / probe code
For distributions, we need one place where we can decide
which driver will be activated for the auto-configation of the
Intel's HDA hardware with DSP. Actually, we cover three drivers:

* Legacy HDA
* Intel SST
* Intel Sound Open Firmware (SOF)

All those drivers registers similar PCI IDs, so the first
driver probed from the PCI stack can win. But... it is not
guaranteed that the correct driver wins.

This commit changes Intel's NHLT ACPI module to a common
DSP probe module for the Intel's hardware. All above sound
drivers calls this code. The user can force another behaviour
using the module parameter 'dsp_driver' located in
the 'snd-intel-dspcfg' module.

This change allows to add specific dmi checks for the specific
systems. The examples are taken from the pull request:

  https://github.com/thesofproject/linux/pull/927

19abfefd4c ALSA: hda: Direct MMIO accesses
HD-audio drivers access to the mmio registers indirectly via the
corresponding bus->io_ops callbacks.  This is because some platform
(notably Tegra SoC) requires the word-aligned access.  But it's rather
a rare case, and other platforms suffer from the penalties by indirect
calls unnecessarily.

This patch is an attempt to optimize and cleanup for this situation.
Now the special aligned access is used only when a new kconfig
CONFIG_SND_HDA_ALIGNED_MMIO is set.  And the HD-audio core itself
provides the aligned MMIO access helpers instead of the driver side.
If Kconfig isn't set (as default), the standard helpers like readl()
or writel() are used directly.

A couple of places in ASoC Intel drivers have the access via io_ops
reg_writel(), and they are replaced with the direct writel() calls.

And now with this patch, the whole bus->io_ops becomes empty, so it's

ASoC: Intel: Skylake: Merge skl_sst and skl into skl_dev struct
Skylake driver is divided into two modules:
- snd_soc_skl
- snd_soc_skl_ipc

and nothing would be wrong if not for the fact that both cannot exist
without one another. IPC module is not some kind of extension, as it is
the case for snd_hda_ext_core which is separated from snd_hda_core -
legacy hda interface. It's as much core Skylake module as snd_soc_skl
is.

Statement backed up by existence of circular dependency between this
two. To eliminate said problem, struct skl_sst has been created. From
that very momment, Skylake has been plagued by header errors (incomplete
structs, unknown references etc.) whenever something new is to be added
or code is cleaned up.

As this design is being corrected, struct skl_sst is no longer needed,
so combine it with struct skl. To avoid ambiguity when searching for skl
stuff (struct skl *skl) it has also been renamed to skl_dev.

No functional changes.

687ae9e287 ASoC: intel: skl: Fix display power regression
Since the refactoring of HD-audio display power management, the
display power status is managed per domain.  Meanwhile the ASoC
hdac_hdmi driver still keeps and relies (incorrectly) on the
refcounting together with ASoC skl driver, and this leads to the
display state always on.

This patch is an attempt to address the regression by simplifying the
PM code of ASoC skl and hdac_hdmi drivers.  Basically, since the
refactoring, we don't have to manage the display power at HD-audio
controller suspend / resume but only at HD-audio HDMI codec suspend /
resume.  So the patch drops the superfluous snd_hdac_display_power()
calls in skl driver.

Meanwhile, in hdac_hdmi side, we rewrite the PM call just to re-use
the runtime PM callbacks like other drivers do.  Now the logic is
simple: turn off at suspend and turn on at resume.

The patch also fixes the possibly missing display-power off at skl
driver removal as well as some error paths at probe.

d82b51c855 ALSA: HD-Audio: SKL+: force HDaudio legacy or SKL+ driver selection
For HDaudio and Skylake drivers, add module parameter "pci_binding"

When pci_binding == 0 (AUTO), the PCI class/subclass info is used to
select drivers based on the presence of the DSP.

pci_binding == 1 (LEGACY) forces the use of the HDAudio legacy driver,
even if the DSP is present.

pci_binding == 2 (ASOC) forces the use of the ASOC driver. The
information on the DSP presence is bypassed.

The value for the module parameter needs to be identical for both
drivers. This parameter is intended as a back-up solution if the
automatic detection fails or when the DSP usage fails. Such cases
should be reported on the alsa-devel mailing list for analysis.

ASoC: Intel: Skylake: Add more platform granularity
The current SKYLAKE kconfig is a all-you-can-eat selection that will
support all known plaforms. This is however not necessarily a good
thing: most platforms for SKL and KBL don't support the DSP, but a
number of CNL/WHL ones do. Selecting this driver in all cases isn't
really smart and will require users to muck with blacklists.

Partition the configs to allow distributions to select on which
platform this driver is used. Keep the existing SND_SOC_INTEL_SKYLAKE
config to select everything for backwards compatibility. This patch does
not provide new functionality, only finer-grained choices in supported
platforms.

029d92c289 ALSA: hda: Refactor display power management
The current HD-audio code manages the DRM audio power via too complex
redirections, and this seems even still unbalanced in a corner case as
Intel DRM CI has been intermittently reporting.  This patch is a big
surgery for addressing the complexity and the possible unbalance.

Basically the patch changes the display PM in the following ways:

- Both HD-audio controller and codec drivers call a single helper,
  snd_hdac_display_power().  (Formerly, the display power control from
  a codec was done indirectly via link_power bus ops.)

- snd_hdac_display_power() receives the codec address index.  For
  turning on/off from the controller, pass HDA_CODEC_IDX_CONTROLLER.

- snd_hdac_display_power() doesn't manage refcounts any longer, but
  keeps the power status in bitmap.  If any of controller or codecs is
  turned on, the function updates the DRM power state via get_power()
  or put_power().

Also this refactor allows us more cleanup:

- The link_power bus ops is dropped, so there is no longer indirect
  management, as mentioned in the above.

- hdac_device link_power_control flag is moved to hda_codec
  display_power_control flag, as it's only for HDA legacy.
