      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.

      ALSA: hda/realtek - Change EAPD to verb control · 394c97f8
      由 Kailang Yang 提交于 
      This will fix no sound in Linux system after reboot from windows.

Change log:
- alc662_fill_coef() is replaced with alc_fill_eapd_coef_idx()
  and move into alc_auto_init_amp().
- For ALC262, ALC267, ALC268, ALC269, ALC233, ALC255, ALC280, ALC282,
  ALC283, ALC284, ALC285, ALC286, ALC288, ALC290, ALC292, ALC293, ALC294,
  ALC668, ALC888VC, ALC888VD, ALC891, ALC892, ALC898 and ALC1150, add update
  COEF control for EAPD setting.
- Remove alc269_fill_coef() for update EAPD control line.

ADDITIONAL NOTE:
Many Realtek cdoecs have a COEF bit to switch the master amp control
between COEF and EAPD.  Windows drivers seem using COEF while we use
EAPD, which is more standard.  As a result, some system suffer from
the silent output when booting after Windows.  This patch sets the
COEF bits on the relevant codecs properly to switch to EAPD control.

      ALSA: hda - Allow multiple callbacks for jack · 1a4f69d5
      由 Takashi Iwai 提交于 
      So far, hda_jack infrastructure allows only one callback per jack, and
this makes things slightly complicated when a driver wants to assign
multiple tasks to a jack, e.g. the standard auto-mute with a power
up/down sequence.  This can be simplified if the hda_jack accepts
multiple callbacks.

This patch is such an extension: the callback-specific part (the
function and private_data) is split to another struct from
hda_jack_tbl, and multiple such objects can be assigned to a single
hda_jack_tbl entry.

The new struct hda_jack_callback is passed to each callback function
now, thus the patch became bigger than expected.  But these changes
are mostly trivial.

      ALSA: hda - Get rid of action field from struct hda_jack_tbl · 62f949bf
      由 Takashi Iwai 提交于 
      The action value assigned to each hda_jack_tbl entry is mostly
superfluous.  The actually used values are either the widget NID or a
value specific to the callback.

The former case can be simply replaced by a reference to widget NID
itself.  The only place doing the latter is STAC/IDT codec driver for
the powermap handling.  But, the code doesn't need to check the action
field at all -- the function jack_update_power() is called either with
a specific pin or with NULL.  So the check of jack->action can be
removed completely there, too.
