      ALSA: hda - Fix click noise at start on Dell XPS13 · 3e1b0c4a
      由 Takashi Iwai 提交于 
      Dell XPS13 produces a click noise at boot up, and Gabriele spotted out
that it's triggered by the initial pin control of the mic (NID 0x19).
This has to be set to Hi-Z Vref while the driver initializes to Vref
80% as a normal mic.

This patch fixes the generic parser code not to override the target
vref if it has been already set by the driver, and adds a proper
initialization of the target vref for this pin in the Realtek driver
side.

      ALSA: hda/realtek - Fix the regression by widget power-saving · cffd3966
      由 Takashi Iwai 提交于 
      While enabling the widget power-saving for ALC269 & co, the important
setup was forgotten -- stream_pm ops.  Without this setup, the paths
for PCM won't be powered up at all.

Also, the power_filter callbacks used in ALC269 & co need to chain to
the default snd_hda_gen_path_power_filter().

      ALSA: hda - Fix headphone pin config for Lifebook T731 · cc7016ab
      由 Takashi Iwai 提交于 
      Some BIOS version of Fujitsu Lifebook T731 seems to set up the
headphone pin (0x21) without the assoc number 0x0f while it's set only
to the output on the docking port (0x1a).  With the recent commit
[03ad6a8c: ALSA: hda - Fix "PCM" name being used on one DAC when
 there are two DACs], this resulted in the weird mixer element
mapping where the headphone on the laptop is assigned as a shared
volume with the speaker and the docking port is assigned as an
individual headphone.

This patch improves the situation by correcting the headphone pin
config to the more appropriate value.

      ALSA: hda - Use regmap for command verb caches, too · a551d914
      由 Takashi Iwai 提交于 
      Like the previous patches, this patch converts also to the regmap, at
this time, the cached verb writes are the target.  But this conversion
needs a bit more caution than before.

- In the old code, we just record any verbs as is, and restore them at
  resume.  For the regmap scheme, this doesn't work, since a few verbs
  like AMP or DIGI_CONVERT are asymmetrical.  Such verbs are converted
  either to the dedicated function (snd_hda_regmap_xxx_amp()) or
  changed to the unified verb.

- Some verbs have to be declared as vendor-specific ones before
  accessing via regmap.

Also, the minor optimization with codec->cached_write flag is dropped
in a few places, as this would confuse the operation.  Further
optimizations will be brought in the later patches, if any.

This conversion ends up with a drop of significant amount of codes,
mostly the helper codes that are no longer used.

      ALSA: hda - Use regmap for amp accesses · eeecd9d1
      由 Takashi Iwai 提交于 
      This patch converts the amp access functions to the regmap helpers.
The amp values were formerly cached in the own hash table.  Now it's
dropped by the regmap's cache.

The only tricky conversion is snd_hda_codec_amp_init().  This function
shouldn't do anything if the amp was already initialized.  For
achieving this behavior, a value is read once at first temporarily in
the cache-only mode.  Only if it returns an error,  i.e. the item
still doesn't exist in the cache, it proceeds to the update.

      ALSA: hda - Move a part of hda_codec stuff into hdac_device · 7639a06c
      由 Takashi Iwai 提交于 
      Now some codes and functionalities of hda_codec struct are moved to
hdac_device struct.  A few basic attributes like the codec address,
vendor ID number, FG numbers, etc are moved to hdac_device, and they
are accessed like codec->core.addr.  The basic verb exec functions are
moved, too.

      ALSA: hda - Simplify PCM setup overrides · fb83b635
      由 Takashi Iwai 提交于 
      This patch does two things:
- code refactoring with a local helper function,
- allow codec drivers to provide the specific PCM stream info pointers
  only for overriding the non-NULL entries, instead of copying the
  whole.

This simplifies the codec driver side (currently the only user is
alc269's 44kHz fixed rate).

      ALSA: hda - Allocate hda_pcm objects dynamically · bbbc7e85
      由 Takashi Iwai 提交于 
      So far, the hda_codec object kept the hda_pcm list in an array, and
the codec driver was expected to assign the array.  However, this
makes the object life cycle management harder, because the assigned
array is freed at the codec driver detach while it might be still
accessed by the opened streams.

In this patch, we allocate each hda_pcm object dynamically and manage
it as a linked list.  Each object has a kref refcount, and both the
codec driver binder and the PCM open/close touches it, so that the
object won't be freed while in use.

      ALSA: hda - Bind codecs via standard bus · d8a766a1
      由 Takashi Iwai 提交于 
      Now we create the standard HD-audio bus (/sys/bus/hdaudio), and bind
the codec driver with the codec device over there.  This is the first
step of the whole transition so that the changes to each codec driver
are kept as minimal as possible.

Each codec driver needs to register hda_codec_driver struct containing
the currently existing preset via the new helper macro
module_hda_codec_driver().  The old hda_codec_preset_list is replaced
with this infrastructure.  The generic parsers (for HDMI and other)
are also included in the preset with the special IDs to bind
uniquely.

In HD-audio core side, the device binding code is split to
hda_bind.c.  It provides the snd_hda_bus_type implementation to match
the codec driver with the given codec vendor ID.  It also manages the
module auto-loading by itself like before: when the matching isn't
found, it tries to probe the corresponding codec modules, and finally
falls back to the generic drivers.  (The special ID mentioned above is
set at this stage.)

The only visible change to outside is that the hdaudio sysfs entry now
appears in /sys/bus/devices, not as a sound class device.

More works to move the suspend/resume and remove ops will be
(hopefully) done in later patches.

      ALSA: hda - Select INPUT for Realtek HD-audio codec · ffcd28d8
      由 Takashi Iwai 提交于 
      The commit commit [33f4acd3: ALSA: hda - Enable mic mute hotkey
and LEDs for an HP machine] introduced a quirk for a HP machine
involving with the input event handling.  Although the relevant code
is protected via IS_ENABLED(CONFIG_INPUT), this doesn't suffice when
the audio driver is built in while the input is module.

As an easy workaround, this patch forcibly selects CONFIG_INPUT in
Kconfig.  This shouldn't be a practical problem since CONFIG_INPUT is
almost mandatory for all systems.  Also, this allows to remove the
ugly ifdefs in the code.
