This patch is a cleanup to the previous patch "reset hda link during system/
runtime suspend".

In this patch
- azx_enter_link_reset() and azx_exit_link_reset() are defined for entering and
  exiting the link reset respectively. azx_link_reset() is no longer used and
  replaced by azx_enter_link_reset().
- azx_reset() reuses the above two new functions for a link reset cycle

eb33ccf763 ALSA: hda - Use auto_mute_via_amp=1 for VT1708
We've got bug report wrt many machines with VT1708 (e.g. IBM POS
machines) showing the broken auto-mute behavior.  It turned out that
the problem is that the pin control values of the speaker and line-out
pins are completely ignored.  As a workaround, let's use the newly
introduced feature of the generic parser, to control the mute via amp
on pins.

7eebffd3f4 ALSA: hda - Add auto_mute_via_amp flag to generic parser
Add a new flag, auto_mute_via_amp, to determine the behavior of the
headphone / line-out auto-mute.  When this flag is set, the generic
driver mutes the speaker and line outputs via the amp mute of each
pin, instead of changing the pin control values.

This is introduced for devices that don't work expectedly with the pin
control values; for example, some devices are known to keep enabling
the speaker outputs no matter which pin control values are set on the
speaker pins.

The driver doesn't check actually whether the pins have the output amp
caps, but assumes that the proper mixer (mute) controls are created on
all these pins.  If not the case, you can't use this flag for your
device.

3af3f356e1 ALSA: hda - reset hda link during system/runtime suspend
If all the codecs report ClkStopOK (OK to stop bus clock) after being put to
D3, this patch will reset the HDA link before the controller is put to D3.

So the link will be in reset during system or runtime suspend, the bus clock
stops and the codecs are in D3(ClkStop) state.

This may help to reduce power consumption by dozens of mW on some peripheral
hda codecs.

d045c5dc43 ALSA: hda - Fix missing Mic Boost controls for VIA codecs
Some VIA codecs like VT1708S have Mic boost amps in the mic pins but
they aren't exposed in the capability bits.  In the past driver code,
we override the pin caps and create mic boost controls forcibly.
While transition to the generic parser, we lost the mic boost controls
although the pin caps are still overridden, because the generic parser
code checks the widget caps, too.

So this patch adds a new helper function to allow the override of the
given widget capability bits, and makes VIA codecs driver to add the
missing input-amp capability bit.

06ec56d3c6 ALSA: hda - Fix return value of snd_hda_check_power_state()
The refactoring by commit 9040d102 introduced the new function
snd_hda_check_power_state().  This function is supposed to return true
if the state already reached to the target state, but it actually

Fortunately this didn't influence on much behavior because powering up
AFG usually powers up the child widgets, too.  But the finer power
control must have been broken by this bug.

63e51fd708 ALSA: hda - Don't take unresponsive D3 transition too serious
When a codec is powered off, some systems don't respond properly after
D3 FG transition, while the driver still expects the response and
tries to fall back to different modes (polling and single-cmd).  When
the fallback happens, the driver stays in that mode, and falling back
to the single-cmd mode means it'll loose the unsol event handling,
too.

The unresponsiveness at D3 isn't too serious, thus this fallback is
mostly superfluous.  We can gracefully ignore the error there so that
the driver keeps the normal operation mode.

This patch adds a new bit flag for codec read/write, set in the power
transition stage, which is notified to the controller driver via a new
bus->no_response_fallback flag.

e7ecc27e52 ALSA: hda - Introduce bit flags to snd_hda_codec_read/write()
snd_hda_codec_read(), snd_hda_codec_write() & co take the argument
"direct" that indicates whether the given NID is a direct reference or
an indirect reference.  However, the indirect reference is practically
unimplemented and never exists.  And moreover, we don't need the
indication of indirect reference at this high level, as NID can be
represented in 16bit values at this point.

Meanwhile, there are some cases where it'd be nice to give some
operational options to these functions.  So, we can reuse this
argument as a new bit flag!  Pretty frugal, eh?

All callers so far pass zero to this argument, thus there is no
behavior change by this replacement.

The real usage of this new bit option will be added in the following
patches.

36bb00d4b2 ALSA: hda - Drop hard dependency on CONFIG_SND_DYNAMIC_MINORS
Currently HDMI codec driver sets the hard dependency (reverse
selection) on CONFIG_SND_DYNAMIC_MINORS because the recent codecs may
support more than two PCMs.  But, this doesn't mean that we need
always this option, since there can be a single PCM stream even with
the modern codecs.

error message when no enough PCMs are available due to the lack of

5a6f294e87 ALSA: hda/via - Fix wrongly cleared pins after suspend on VT1802
VIA driver has a special suspend handling only for VT1802 to reduce
the pop noise.  During the transition to the generic parser, the
behavior of snd_hda_set_pin_ctl() was also changed to modify the
cached values, too.  And this caused a regression where the pin is
still cleared even after the resume (including the resume from power
save), resulting in the silent output.

The fix is simply to replace snd_hda_set_pin_ctl() with the explicit
call of snd_hda_codec_write() again.

17df3f5565 ALSA: hda - Apply pin-enablement workaround to all Haswell HDMI codecs
This is a revised patch based on Mengdong Lin's fix patch, which is a
supplement to a previous patch [1611a9c9: ALSA: hda - Add fixup for
Haswell to enable all pin and convertor widgets].

Some Haswell BIOS will disable the 2nd and 3rd pin/covertor widgets
when the HD-A controller changes state from D3 to D0.  So when the
controller resumes after a system or runtime suspend, these widgets
are disabled and programming these widgets to D0 will cause H/W error
and codec will not respond.

In addition, we found out that some BIOS disables the pins at S3
although it shows up at boot.  This confuses the driver utterly, and
the hardware falls into the fatal communication error like the above.

So in this patch, we apply intel_haswell_enable_all_pins() not only as
a fixup to a certain device (with 8086:2010) but to all Haswell
machines.  The codec driver basically assumes that all pins are
exposed, so it's anyway better to see them from the beginning.  Even
if all pins and converters are shown by this call, there should be no
regression in practice: the pin default configurations are still kept,
thus the disabled pins are handled as disabled by the driver
properly.

2195b063f6 ALSA: HDA: Fix Oops caused by dereference NULL pointer
The interrupt handler azx_interrupt will call azx_update_rirb,
which may call snd_hda_queue_unsol_event, snd_hda_queue_unsol_event
will dereference chip->bus pointer.

The problem is we alloc chip->bus in azx_codec_create
which will be called after we enable IRQ and enable unsolicited
event in azx_probe.

This will cause Oops due dereference NULL pointer. I meet it, good luck:)

[Rearranged the NULL check before the tracepoint and added another
 NULL check of bus->workq -- tiwai]

ff359b1491 ALSA: hda - Fix 3.9 regression of EAPD init on Conexant codecs
The older Conexant codecs have up to two EAPDs and these are supposed
to be rather statically turned on.  The new generic parser code
assumes the dynamic on/off per path usage, thus it resulted in the
silent output on some machines.

This patch fixes the problem by simply assuming the static EAPD on for
such old Conexant codecs as we did until 3.8 kernel.

49d9e77e72 ALSA: hda - Fix system panic when DMA > 40 bits for Nvidia audio controllers
The audio driver mistakenly allows 64 bit addresses to be created for
the audio driver on Nvidia GPUs.  Unfortunately, the hardware normally
only supports up to 40 bits of DMA.  This can cause system panics as
well as misdirected data when the address is > 40 bits as the upper
part the address is truncated.

This enables better volume controls than the current model parser.
Also, because the original quirk for X220 was added to fix
docking station support, add the TP410 fixup instead.

d5657ec9f4 ALSA: hda - Disable the sanity check in snd_hda_add_pincfg()
When pin default configs are overridden via patch option, these are
evaluated before fixups are applied.  Since some fixups change the
whole codec trees and/or add pins dynamically, this sanity check might
not pass when pins aren't present at the time the function is called.

We may reorder the execution, but an easier fix is simply to disable
this sanity check.
