a2d96e778d ALSA: hda - More robustify the power-up/down sequence
Check the power_transition up/down state instead of boolean bit, so
that the power-up sequence can cancel the pending power-down work
properly.  Also, by moving cancel_delayed_work_sync() before the
actual power-up sequence, make sure that the delayed power-down is
completed.

Since the recent commit, the resume procedure is always performed at
the resume time.  This makes the pre_resume hack for VREF mute LED on
some HP laptops superfluous.  As this is the only user of pre_resume
(and there is no user of post_suspend) ops, let's kill them again.

7f30830b7b ALSA: hda - Always resume the codec immediately
This is a fix for the problem in commit 785f857d1c, the pop noise
issue on some machines with ALC269.  The problem was the uninitialized
state after the resume due to the delayed resume of the codec chips.
In that commit, we tried to fix by forcibly putting the codec to D3 at
suspend.  But, this still also leaves the uninitialized state after
resume, and it _might_ be still problematic with some BIOS.  Since the
commit turned out to regress another issues, we reverted it in the
end.

Now, in this fix, try to fix by turning on the codec immediately at
the resume path.  We need to take care of the power-saving in this
case.  When the device is woken up at the power-saved state, it should
go power-saving again after the resume.

619a341b78 Revert "ALSA: hda - Set codec to D3 forcibly even if not used"
This reverts commit 785f857d1c.

The commit causes a problem with the wrong D3 state after suspend
because the call of hda_set_power_state() involves with the power-up
sequence, which changes the power_count, and this confuses the resume
sequence that checks the power_count as well.

Originally, this go-to-D3 sequence should be a simple task without the
power-up sequence.  But, it'd need some proper sanity checks in the
case of power-saved state, so it's not too easy to write now in the
3.4-rc cycle.

In short, the safest option now is to revert this affecting commit.

Of course, we need to clean up and robustify the power-saving code
better for 3.5 kernel.

cdd03cedc5 ALSA: hda - Introduce snd_hda_set_pin_ctl*() helper functions
For setting the pin-control values more safely to match with the
actual pin capability bits, a copule of new helper functions,
snd_hda_set_pin_ctl() and snd_hda_set_pin_ctl_cache(), are

AC_VERB_SET_PIN_WIDGET but do more sanity checks and filter out
superfluous pin-control bits if they don't fit with the corresponding
pin capabilities.

Some codecs are screwed up or ignore the command when such a wrong bit
is set.  These helpers will avoid such secret errors.

18478e8b62 ALSA: hda - Initialize vmaster slave volumes
When the driver is changed to use vmaster or a new slave element is
added by the improvement of the parser code, user may face often the
silent output because of the muted slave mixer although Master volume
is properly set.  And they complain.  And I get upset.

Although such a mixer element should be initialized via "alsactl init",
it'd be more user-friendly if the known output slaves are unmuted and
set to 0dB so that user can control the volume only with Master as
default.  Since Master is still set muted as default even with this
change, no risk of the speaker blow up, too.

785f857d1c ALSA: hda - Set codec to D3 forcibly even if not used
We've seen a problem with a pop-noise at suspend/resume on a HP
machine with ALC269, and it turned out to be an issue that the
controller going to D3 while the codec is unused.

When the device is once suspended and resumed and kept unused, the
driver doesn't initialize the codecs.  Instead, the codec chips are
set up dynamically at the first usage.  Now, suppose the device going
to suspend again before the codec is set up.  The controller is turned
off to D3 while the codec chips are untouched.  This caused a pop
noise because the codec chip might have been turned on implicitly by
the hardware.

As a workaround, the codec chip needs to be set to D3 when going to
suspend no matter whether it was used or not.  Also, for making it
happening, the controller has to be always set up in the resume path.

3868137ea4 ALSA: hda - Add a fake mute feature
Some codecs don't supply the mute amp-capabilities although the lowest
volume gives the mute.  It'd be handy if the parser provides the mute
mixers in such a case.

This patch adds an extension amp-cap bit (which is used only in the
driver) to represent the min volume = mute state.  Also modified the
amp cache code to support the fake mute feature when this bit is set
but the real mute bit is unset.

In addition, conexant cx5051 parser uses this new feature to implement
the missing mute controls.

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.

We disabled the check of NO_PRESENCE bit of the default pin-config
in commit f4419172 temporarily.  One problem was that the first
implementation was wrong -- the bit after the shift must be checked.
However, this would still give many regressions on machines with broken
BIOS.  They set this bit wrongly even on active pins.

A workaround is to check whether all pins contain this bit.  As far as
I've checked, broken BIOSen set this bit on all pins, no matter whether
active or not.  In such a case, the driver should ignore this bit check.

384a48d715 ALSA: hda: HDMI: Support codecs with fewer cvts than pins
The general concept of this change is to create a PCM device for each
pin widget instead of each converter widget. Whenever a PCM is opened,
a converter is dynamically selected to drive that pin based on those
available for muxing into the pin.

The one thing this model doesn't support is a single PCM/converter
sending audio to multiple pin widgets at once.

Note that this means that a struct hda_pcm_stream's nid variable is
set to 0 except between a stream's open and cleanup calls. The dynamic
de-assignment of converters to PCMs occurs within cleanup, not close,
in order for it to co-incide with when controller stream IDs are
cleaned up from converters.

While the PCM for a pin is not open, the pin is disabled (its widget
control's PIN_OUT bit is cleared) so that if the currently routed
converter is used to drive a different PCM/pin, that audio does not
leak out over a disabled pin.

We use the recently added SPDIF virtualization feature in order to
create SPDIF controls for each pin widget instead of each converter
widget, so that state is specific to a PCM.

In order to support this, a number of more mechanical changes are made:

* s/nid/pin_nid/ or s/nid/cvt_nid/ in many places in order to make it
  clear exactly what the code is dealing with.

* We now have per_pin and per_cvt arrays in hdmi_spec to store relevant
  data. In particular, we store a converter's capabilities in the per_cvt
  entry, rather than relying on a combination of codec_pcm_pars and
  the struct hda_pcm_stream.

* ELD-related workarounds were removed from hdmi_channel_allocation
  into hdmi_instrinsic in order to simplifiy infoframe calculations and
  remove HW dependencies.

* Various functions only apply to a single pin, since there is now
  only 1 pin per PCM. For example, hdmi_setup_infoframe,
  hdmi_setup_stream.

* hdmi_add_pin and hdmi_add_cvt are more oriented at pure codec parsing
  and data retrieval, rather than determining which pins/converters
  are to be used for creating PCMs.

This is quite a large change; it may be appropriate to simply read the
result of the patch rather than the diffs. Some small parts of the change
might be separable into different patches, but I think the bulk of the
change will probably always be one large patch. Hopefully the change
isn't too opaque!

This has been tested on:

* NVIDIA GeForce 400 series discrete graphics card. This model has the
  classical 1:1:1 codec:converter:pcm widget model. Tested stereo PCM
  audio to a PC monitor that supports audio.

* NVIDIA GeForce 520 discrete graphics card. This model is the new
  1 codec n converters m pins m>n model. Tested stereo PCM audio to a
  PC monitor that supports audio.

* NVIDIA GeForce 400 series laptop graphics chip. This model has the
  classical 1:1:1 codec:converter:pcm widget model. Tested stereo PCM,
  multi-channel PCM, and AC3 pass-through to an AV receiver.

* Intel Ibex Peak laptop. This model is the new 1 codec n converters m
  pins m>n model. Tested stereo PCM, multi-channel PCM, and AC3 pass-
  through to an AV receiver.

Note that I'm not familiar at all with AC3 pass-through. Hence, I may
not have covered all possible mechanisms that are applicable here. I do
know that my receiver definitely received AC3, not decoded PCM. I tested
with mplayer's "-afm hwac3" and/or "-af lavcac3enc" options, and alsa a
WAV file that I believe has AC3 content rather than PCM.

I also tested:
* Play a stream
* Mute while playing
* Stop stream
* Play some other streams to re-assign the converter to a different
  pin, PCM, set of SPDIF controls, ... hence hopefully triggering
  cleanup for the original PCM.
* Unmute original stream while not playing
* Play a stream on the original pin/PCM.

This was to test SPDIF control virtualization.

74b654c957 ALSA: hda: Virtualize SPDIF out controls
The SPDIF output controls apply to converter widgets. A future change
will create a PCM device per pin widget, and hence a set of SPDIF output
controls per pin widget, for certain HDMI codecs. To support this, we
need the ability to virtualize the SPDIF output controls. Specifically:

* Controls can be "unassigned" from real hardware when a converter is
  not used for the PCM the control was created for.
* Control puts only write to hardware when they are assigned.
* Controls can be "assigned" to real hardware when a converter is picked
  to support output for a particular PCM.
* When a converter is assigned, the hardware is updated to the cached
  configuration.

7c93597627 ALSA: hda: Allow multple SPDIF controls per codec
Currently, the data that backs the kcontrols created by
snd_hda_create_spdif_out_ctls is stored directly in struct hda_codec. When
multiple sets of these controls are stored, they will all manipulate the
same data, causing confusion. Instead, store an array of this data, one
copy per converter, to isolate the controls.

This patch would cause a behavioural change in the case where
snd_hda_create_spdif_out_ctls was called multiple times for a single codec.
As best I can tell, this is never the case for any codec.

This will be relevant at least for some HDMI audio codecs, such as the
NVIDIA GeForce 520 and Intel Ibex Peak. A future change will modify the
driver's handling of those codecs to create multiple PCMs per codec. Note
that this issue isn't affected by whether one creates a PCM-per-converter
or PCM-per-pin; there are multiple of both within a single codec in both
of those codecs.

Note that those codecs don't currently create multiple PCMs for the codec
due to the default HW mux state of all pins being to point at the same
converter, hence there is only a single converter routed to any pin, and
hence only a single PCM.

de8c85f784 ALSA: HDA: Sigmatel: work around incorrect master muting
The HDA specification does not allow for a codec to mute itself just
because the volume is reduced, so _of course_ somebody had to go and do
it.  This wouldn'\''t hurt too much when the volume is adjusted by hand,
but programs like PA that try to set the volume automatically could
inadvertently mute the output.

To work around this, change the TLV dB information for the Master volume
on all Sigmatel HDA codecs to indicate the the minimal volume setting
actually mutes.

moved to struct hda_bus, as this becomes also bus-wide.
