David Henningsson 80c8bfbe76 ALSA: HDA: Create phantom jacks for fixed inputs and outputs
PulseAudio sometimes have difficulties knowing that there is a
"Speaker" or "Internal Mic", if they have no individual volume
controls or selectors. As a result, only e g "Headphone" might
be created for a laptop, but no "Speaker".
To help out, create phantom jacks (that are always present,
at least for now) for "Speaker", "Internal Mic" etc, in case we
detect them.
The naming convention is e g "Speaker Phantom Jack".

In order not to pollute the /dev/input namespace with even more
devices, these are added to the kcontrols only, not the input devices.

Takashi Iwai 71b1e9e43d ALSA: hda - Add codec->no_jack_detect flag
Add a new flag to indicate that the codec has no jack-detection cap.
This flag should be set for hardwares that have no jack-detect
implementation although the codec chip itself supports it.

David Henningsson 05c3b36e53 ALSA: HDA: Fix jack creation for codecs with front and rear Line In
If a codec has both a front and a rear Line In, two controls both
named "Line Jack" will be created, which causes parsing to fail.
While a long term solution might be to name the jacks differently,
this extra check is consistent with what is already being done in many
auto-parsers, and will also protect against other cases when two
inputs have the same label.

Takashi Iwai 31ef225793 ALSA: hda - Integrate input-jack stuff into kctl-jack
Instead of managing input-jack stuff separately, call all stuff inside
the kctl-jack creation, deletion and report.  The caller no longer needs
to care about input-jack.

The better integration between input-jack and kctl-jack should be done
in the upper layer in near future, but for now, it's implemented locally
for more tests.

Takashi Iwai 201e06ffa9 ALSA: hda - Give more unique names by snd_hda_get_pin_label()
The function now gives more unique names for the output pins by adding
some prefix and suffix for the location and the channels.  Otherwise, it
can pass the index number.

Takashi Iwai 35be544af3 ALSA: Introduce common helper functions for jack-detection control
Now move the helper function for creating and reporting the jack-detection
to the common place.  The driver that needs this functionality should
select CONFIG_SND_KCTL_JACK kconfig.

Takashi Iwai 3a93897ea3 ALSA: hda - Manage unsol tags in hda_jack.c
Manage the tags assigned for unsolicited events dynamically together
with the jack-detection routines.  Basically this is almost same as what
we've done in patch_sigmatel.c.  Assign the new tag number for each new
unsol event, associate with the given NID and the action type, etc.

With this change, now all pins looked over in snd_hda_jack_add_kctls()
are actually enabled for detection now even if the pins aren't used for
jack-retasking by the driver.

Takashi Iwai 01a61e12b4 ALSA: hda - Create jack-detection kcontrols
Create kcontrols for pin jack-detections, which work similarly like
jack-input layer.  Each control will notify when the jack is plugged or
unplugged, and also user can read the value at any time via the normal
control API.

The control elements are created with iface=CARD, so that they won't
appear in the mixer apps.

So far, only the pins that enabled the jack-detection are registered.
For covering all pins, the transition of the common unsol-tag handling
would be needed.  Stay tuned.

Takashi Iwai 1835a0f9a2 ALSA: hda - Cache the jack-detection value
Introduce a table containing the pins and their jack-detection states
for avoiding the unnecessary verbs to check the pin status at each time.

When the unsol event is enabled via snd_hda_jack_detect_enable(), it
automatically adds the given NID to the table.  Then the driver supposes
that the codec driver will set the dirty flag appropariately when an
unsolicited event is invoked for that pin.

The behavior for reading other pins that aren't registered in the table
doesn't change.  Only the pins assigned to the table are cached, so far.

In near futre, this table can be extended to use the central place for
the unsolicited events of all pins, etc, and eventually include the
jack-detect kcontrols that replace the current input-jack stuff.
