Takashi Iwai b9a94a9c78 ALSA: hda - convert to hda_device_id
Finally we have a proper infrastructure to generate the modaliases
automatically, let's move to hda_device_id from the legacy
hda_codec_preset that contains basically the same information.

The patch function hook is stored in driver_data field, which is long,
and we need an explicit cast.  Other than that, the conversion is
mostly straightforward.  Each entry is even simplified using a macro,
and the lengthy (and error-prone) manual modaliases got removed.

As a result, we achieved a quite good diet:

Takashi Iwai 225068ab27 ALSA: hda - Set patch_ops before calling auto-parser
... so that the parser code can overwrite some optional ops.  For
Realtek and others, it can be set solely in the spec allocator, so it
results in a good code cleanup, too.

With this change, we can finally remove the local stream_pm setup and
rely on the generic parser's automatic setting.

Takashi Iwai a551d91473 ALSA: hda - Use regmap for command verb caches, too
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.

Takashi Iwai 7639a06c23 ALSA: hda - Move a part of hda_codec stuff into hdac_device
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.

Takashi Iwai d8a766a16e ALSA: hda - Bind codecs via standard bus
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.

  - Elimination of the ASoC level wrappers for I2C and SPI moving us

    randconfig hassle.
  - Provide both manually and transparently locked DAPM APIs rather than
    a mix of the two fixing some concurrency issues.
  - Start converting CODEC drivers to use separate bus interface drivers
    rather than having them all in one file helping avoid dependency
    issues.
  - DPCM support for Intel Haswell and Bay Trail platforms.
  - Lots of work on improvements for simple-card, DaVinci and the Renesas
    rcar drivers.
  - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
    CSR SiRF SoC.

Takashi Iwai 3690739b01 ALSA: hda - Add static DAC/pin mapping for AD1986A codec
AD1986A codec is a pretty old codec and has really many hidden
restrictions.  One of such is that each DAC is dedicated to certain
pin although there are possible connections.  Currently, the generic
parser tries to assign individual DACs as much as possible, and this
lead to two bad situations: connections where the sound actually
doesn't work, and connections conflicting other channels.

We may fix this by trying to find the best connections more harder,
but as of now, it's easier to give some hints for paired DAC/pin
connections and honor them if available, since such a hint is needed
only for specific codecs (right now only AD1986A, and there will be
unlikely any others in future).

Takashi Iwai 1ac3293095 ALSA: hda - Fix silent headphone on Thinkpads with AD1984A codec
AD1984A codec has a couple of pins with EAPD controls, and the generic
codec driver tries to turn each of them on/off depending on the pin
active state.  However, Thinkpads seem to use EAPD of the speaker pin
as a master EAPD for controlling the mute of all outputs, including
the headphone.  This results in the dead headphone output via the
headphone plugging because it mutes the speaker and turns off EAPD.

The fix is to simply add spec->gen.keep_on_eapd flag.

[This is a regression fix on 3.12 where we moved the AD codec parser
 to the generic parser.  3.11 and earlier didn't show this problem
 because still static quirks have been used.]

This patch changes the function to set spec->eapd_nid after the
generic parser call while it sets vmaster hook unconditionally.  The
spec->eapd_nid check is moved in the hook function itself instead.

Takashi Iwai 7504b6cd22 ALSA: hda - Move beep attach/detach calls in hda_generic.c
Instead of calling snd_hda_attach_beep_device() and
snd_hda_detach_beep_device() in each codec driver, move them to the
generic parser.  The codec driver just needs to set spec->beep_nid for
activating the digital beep.

Takashi Iwai e4a395e781 ALSA: hda - Fix missing path between aamix and outputs in AD codecs
AD1988 family and AD1882 codecs have another mixer widget (0x21)
between the analog-loopback mixer widget (0x20) and the actual
outputs.  Due to this hole, the analog-loopbacks aren't sent properly
to the output pins.

As a band-aid fix, introduce another fields holding the aamix merge
path, and activate it.

Takashi Iwai 657e1b931d ALSA: hda - Select auto-parser as default for AD codecs
Now all AD codecs have the proper BIOS auto-parser, and we can make
it for default, finally.  (AD1988 already did it because it had the
auto-parser.)

Other remaining quirks are mostly resolvable via pincfg fixes, even if
it matters.

Takashi Iwai 9ff4bc8f72 ALSA: hda - Rearrange for dropping static quirk codes in AD codec driver
As done for patch_conexant.c, put ifdef ENABLE_AD_STATIC_QUIRKS for
preparing t odrop the static quirk codes in patch_analog.c.

The whole static quirk code can be omitted by commenting out
ENABLE_AD_STATIC_QUIRKS define now.

Takashi Iwai 272f3ea317 ALSA: hda - Add SPDIF mux control to AD codec auto-parser
AD codecs have strange implementations for choosing the SPDIF-output
mux source: the digital audio out widget may take the sources from
multiple connections, where 0x01 indicates it's a PCM while others
point ADCs.  It's obviously invalid in the HD-audio spec POV, but it's
somehow convincing, too.  And, to make things more complex, AD1988A
and AD1882 have deeper connection routes that aren't expressed
correctly.

In this patch, the SPDIF mux control is implemented in two ways:
- For easier one like AD1981, AD1983, AD1884 and AD1984, where the
  SPDIF audio out widget takes just two or three sources, we can
  simply implement via the normal input_mux and connection verb
  calls.

- For the complex routes like AD1988A (but not AD1988B) or AD1882, we
  prepare "faked" paths represented statically, and switch the paths
  using these static ones, instead of parsing the routes from the
  widget tree.
