a76056f2e5 ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug
Dynamically bind/unbind the PCM to pin when HDMI/DP monitor hotplug.

When monitor is connected, find a proper PCM for the monitor.
When monitor is disconnected, unbind the PCM from the pin.

The binding policy (use Intel platform as example) is:
1. Try to use the legacy pin-pcm mapping for the device entry 0
   of the pin.
2. If step 1 fails, try to bind pin to the backup PCMs. For example,
   on Intel platform, if DP MST is enabled, 5 PCMs will be created.
   PCM 3, PCM 7, PCM 8 are supposed to be used by device entry 0 of
   pin 5, pin 6 and pin 7. PCM 9 and PCM 10 are the backup PCMs.
3. If step 2 fails, try to find any PCM to bind to the pin.

2bf3c85a5b ALSA: hda - hdmi operate spdif based on pcm
Currently, the driver operates the spdif based on pin.
This is ok for the current driver as pcm is statically
bound to the pin.

However, if the driver uses dynamically pcm assignment,
this will cause confusion for user space.

The patch changes spdif operation from pin based to pcm based.

42b2987079 ALSA: hda - hdmi playback without monitor in dynamic pcm bind mode
Pulseaudio requires open pcm successfully when probing.

This patch handles playback without monitor in dynamic pcm assignment
mode. It tries to open/prepare/close pcm successfully even there is
no pin bound to the PCM. On the meantime, it will try to find a proper
converter for the PCM.

As pcm is This patch introduces a pcm_lock in struct hdmi_spec.
This lock is used to protect:
1. the variables in struct hdmi_spec;
2. other variables shared for dynamic pcm assignment mode
3. device entry selection. As each device entry is represented by
   a separate struct struct hdmi_spec_per_pin, the lock in per_pin
   is not enough. Please see details below.

MST audio device entry operation:
1. select device entry on the pin
2. operate on the pin nid

6590faaba4 ALSA: hda - hdmi begin to support dynamic PCM assignment
Begin to support dynamic PCM assignment to pin in
hdmi audio driver.

This means PCM will not be statically bound with pin.
When there is a monitor connected, the corresponding pin
will try to find a proper PCM to bind. When the monitor
is disconnected, the corresponding pin will unbind
the PCM. This helps to reduce the PCM number when there
are many pins (device entries in DP MST mode) and only
a few of them work at the same time.

This patch adds the pcm member in struct hdmi_spec_per_pin.
When PCM is dynamically bound to the pin, the member pcm
will pointer to the corresponding pcm_rec[] in hdmi_spec,
which means the hda_pcm is bound to the pin.

991f86d7ae ALSA: hda - Flush the pending probe work at remove
As HD-audio driver does deferred probe internally via workqueue, the
driver might go into the mixed state doing both probe and remove when
the module gets unloaded during the probe work.  This eventually
triggers an Oops, unsurprisingly.

For avoiding this race, we just need to flush the pending probe work
explicitly before actually starting the resource release.

bca8e98804 ALSA: hda - Fix missing module loading with model=generic option
When the generic codec driver is specified via model option or such,
the hda driver doesn't try to load the generic driver module but still
loads the codec-specific driver, and this ends up with the binding
failure.

This patch fixes it by moving the generic module request in the common
helper code.

bed2e98e1f ALSA: hda - Degrade i915 binding failure message
Currently HD-audio driver on Intel Skylake or Broxteon gives an error
message when binding with i915 audio component fails.  However, this
isn't any serious error on a system without Intel graphics.  Indeed
there are such systems, where a third-party codec (e.g. Creative) is
put on the mobo while using other discrete GPU (e.g. Nvidia).
Printing a kernel "error" message is overreaction in such a case.

This patch downgrades the print level for that message.  For systems
that mandate the i915 binding (e.g. Haswell or Broadwell HDMI/DP),
another kernel error message is shown in addition to make clear what
went wrong.

a016af2e70 sound updates for 4.5-rc1
We've had quite busy weeks in this cycle.  Looking at ALSA core, the
 significant changes are a few fixes wrt timer and sequencer ioctls
 that have been revealed by fuzzer recently.  Other than that, ASoC
 core got a few updates about DAI link handling, but these are rather
 straightforward refactoring.
 
 In drivers scene, ASoC received quite lots of new drivers in addition
 to bunch of updates for still ongoing Intel Skylake support and
 topology API.  HD-audio gained a new HDMI/DP hotplug notification via
 component.  FireWire got a pile of code refactoring/updates with
 SCS.1x driver integration.
 
 More highlights are shown below.
 
 [NOTE: this contains also many commits for DRM.  This is due to the
  pull of drm stable branch into sound tree, as the base of i915 audio
  component work for HD-audio.  The highlights below don't contain
  these DRM changes, as these are supposed to be pulled via drm tree in
  anyway sooner or later.]
 
 Core
  - Handful fixes to harden ALSA timer and sequencer ioctls against
    races reported by syzkaller fuzzer
  - Irq description string can be unique to each card; only for
    HD-audio for now
 
 ASoC
  - Conversion of the array of DAI links to a list for supporting
    dynamically adding and removing DAI links
  - Topology API enhancements to make everything more component based
    and being able to specify PCM links via topology
  - Some more fixes for the topology code, though it is still not final
    and ready for enabling in production; we really need to get to the
    point where that can be done
  - A pile of changes for Intel SkyLake drivers which hopefully deliver
    some useful initial functionality for systems with this chipset,
    though there is more work still to come
  - Lots of new features and cleanups for the Renesas drivers
  - ANC support for WM5110
  - New drivers: Imagination Technologies IPs, Atmel class D speaker,
    Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and
    RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP
  - Rename PCM1792a driver to be generic pcm179x
 
 HD-Audio
  - Use audio component for i915 HDMI/DP hotplug handling
  - On-demand binding with i915 driver
  - bdl_pos_adj parameter adjustment for Baytrail controllers
  - Enable power_save_node for CX20722; this shouldn't lead to
    regression, hopefully
  - Kabylake HDMI/DP codec support
  - Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell
    machines
  - A few code refactoring
 
 FireWire
  - Lots of code cleanup and refactoring
  - Integrate the support of SCS.1x devices into snd-oxfw driver;
    snd-scs1x driver is obsoleted
 
 USB-audio
  - Fix possible NULL dereference at disconnection
  - A regression fix for Native Instruments devices

3694cb2947 ALSA: hda - Add mic mute hotkey quirk for Lenovo ThinkCentre AIO
The Lenovo ThinkCenter AIO uses Line2 (NID 0x1b) to implement the
micmute hotkey, here we register an input device and use Line2 unsol
event to collect the hotkey pressing or releasing.

In the meanwhile, the micmute led is controlled by GPIO2, so we
use an existing function alc_fixup_gpio_mic_mute_hook() to control
the led.

[Hui: And there are two places to register the input device, to make
the code simple and clean, move the two same code sections into a
function.]

3e6db33aaf ALSA: hda - Set SKL+ hda controller power at freeze() and thaw()
It takes three minutes to enter into hibernation on some OEM SKL
machines and we see many codec spurious response after thaw() opertion.
This is because HDA is still in D0 state after freeze() call and
pci_pm_freeze/pci_pm_freeze_noirq() don't set D3 hot in pci_bus driver.
It seems bios still access HDA when system enter into freeze state,
HDA will receive codec response interrupt immediately after thaw() call.
Because of this unexpected interrupt, HDA enter into a abnormal
state and slow down the system enter into hibernation.

In this patch, we put HDA into D3 hot state in azx_freeze_noirq() and
put HDA into D0 state in azx_thaw_noirq().

70a0976b0c ALSA: hda - Set codec to D3 at reboot/shutdown on Thinkpads
Lenovo Thinkpads with Realtek codecs may still have some loud
crackling noises at reboot/shutdown even though a few previous fixes
have been applied.  It's because the previous fix (disabling the
default shutup callback) takes effect only at transition of the codec
power state.  Meanwhile, at reboot or shutdown, we don't take down the
codec power as default, thus it triggers the same problem unless the
codec is powered down casually by runtime PM.

This patch tries to address the issue.  It gives two things:
- implement the separate reboot_notify hook to struct alc_spec, and
  call it optionally if defined.
- turn off the codec to D3 for Thinkpad models via this new callback

2cf721db4b ALSA: hda - Increase default bdl_pos_adj for Baytrail/Braswell
Intel Atom processors seem to have a problem at recording when
bdl_pos_adj is set to an odd value.  When a value like 1 is used, it
may drop the samples unexpectedly.  Actually, for the old Atoms, we
used to set AZX_DRIVER_SCH type, and this assigns 32 as default.
Meanwhile the newer chips, Baytrail and Braswell, are set as
AZX_DRIVER_PCH, and the lower default value, 1, is assigned.

This patch changes the default values for these chipsets to a safer
default, 32, again.  Since changing the driver type (AZX_DRIVER_XXX)
leads to the rename of the driver string, it would result in a
possible regression.  So, we can't change the type.  Instead, in this
patch, manual (ugly) PCI ID checks are added on top.

A drawback by this increase is the slight increase of the latency, but
it's a sub-ms order in normal situations, so mostly negligible.

788d441a16 ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling
Since we have a new audio component ops to fetch the current ELD and
state now, we can reduce the usage of unsol event of HDMI/DP pins.
The unsol event isn't only unreliable, but it also needs the power
up/down of the codec and link at each time, which is a significant
power and time loss.

In this patch, the jack creation and unsol/jack event handling are
modified to use the audio component for the dedicated Intel chips.

The jack handling got slightly more codes than a simple usage of
hda_jack layer since we need to deal directly with snd_jack object;
the hda_jack layer is basically designed for the pin sense read and
unsol events, both of which aren't used any longer in our case.

55913110dd ALSA: hda - Allow i915 binding later in codec driver
Due to the recent change, HDA controller driver for Intel PCH tries to
bind i915 audio component always at the probe time no matter whether
HDMI/DP codec is found.  This is, however, superflulous for old
chipsets (e.g. on IVB) where they don't have always the HDMI/DP codecs
but  often have only a discrete GPU instead.

For the newer chipsets, we need already the i915 binding from the
beginning due to power well control.  Meanwhile, for older chipsets
where we don't need power well, we don't need the i915 binding at the
controller level.

This patch removes again the i915 binding in the HDA controller driver
for old Intel PCHs, but adds the binding in HDMI/DP codec driver
instead.  This allows still the use of the direct notification from
the graphics driver while we can avoid the unnecessary load of i915
driver for machines only with another GPU.
