Since the lock is used primarily in patch_hdmi.c, it's better to move
it in the local struct instead of exporting in hda_eld.  The only
functions requiring the lock in hda_eld.c are proc accessors.  So in
this patch, the proc entry and its creation/deletion/accessors are
moved into patch_hdmi.c, together with the mutex lock to pin_spec
struct.

The former proc info functions are exported so that they can be called
from patch_hdmi.c.

Currently hdmi_setup_audio_infoframe() reprograms the HDA channel
mapping only when the infoframe is not up-to-date or the non-PCM flag
has changed.

However, when just the channel map has been changed, the infoframe may
still be up-to-date and non-PCM flag may not have changed, so the new
channel map is not actually programmed into the HDA codec.

Notably, this failing case is also always triggered when the device is
already in a prepared state and a new channel map is configured while
changing only the channel positions (for example, plain
"speaker-test -c2 -m FR,FL").

Fix that by always programming the channel map in
hdmi_setup_audio_infoframe(). Tested on Intel HDMI.

hdmi_manual_setup_channel_mapping() and hdmi_std_setup_channel_mapping
try to assign ALSA channels to HDMI channel slots and disable (i.e.
silence) other slots.

However, they try to disable a slot by using AC_VERB_SET_CHAN_SLOT with
parameter ((alsa_ch << 8) | 0xf), while the correct parameter is
((0xf << 8) | hdmi_slot), i.e. the slot should be unassigned, not the
ALSA channel.

Fix that by actually disabling the unused slots.

Note that this bug did not cause any (reported) issues because slots
incorrectly having audio are normally ignored by a receiver if the CEA
channel allocation used does not map that slot to any speaker.
Additionally, the converter channel count configuration limits the
number of actually active channels in any case.

Currently the converter channel count is set to the number of actual
input channels. The audio infoframe channel count field is set
similarly.

However, sometimes the used channel map does not map all input channels
to outputs. Notably, 3 channel modes (e.g. 2.1) require a dummy input
channel so there are 4 input channels. According to the HDA
specification, converter channel count should be programmed according to
the number of _active_ channels.

On Intel HDMI codecs (but not on NVIDIA), setting the converter channel
to a higher value than there are actually mapped channels to HDMI slots
will cause no audio to be output at all.

Note that the effects of this issue are currently partially masked by
other bugs that prevent the driver from actually unmapping channels in
certain cases. For example, if a 4 channel stream is first created and
prepared, it gets a FL,FR,RL,RR mapping (ALSA->HDMI slot mapping 0->0,
1->1, 2->4, 3->5). If one thereafter assigns a FR,FL,FC mapping to it,
the driver will remap 2->3 but fail to unmap 2->4 and 3->5, so there are
still 4 active channels and the issue will not trigger in this case.
These bugs will be fixed separately.

Fix the channel counts in the converter channel count field and in the
audio infoframe channel count field to match the actual number of active
channels.

hdmi_std_setup_channel_mapping() selects a Channel Allocation according
to the sink reported speaker mask, preferring the ALSA standard layouts.

If the channel allocation is not one of the ALSA standard layouts, the
ALSA channels are mapped directly to HDMI channels in order. However,
the function does not take into account that there a holes in the HDMI
channel map.

Additionally, the function tries to disable a slot by using
AC_VERB_SET_CHAN_SLOT with parameter ((alsa_ch << 8) | 0xf), while the
correct parameter is ((0xf << 8) | hdmi_slot), i.e. the slot should be
unassigned, not the ALSA channel.

Fix both of the issues for non-ALSA-default layouts.

Tested on Intel HDMI with a speaker mask of FL | FR | FC | RC, which

hdmi_setup_fake_chmap() is supposed to set the reported channel map when
the channel map is not specified by the user.

However, the function indexes channel_allocations[] with a wrong value
and extracts the wrong nibble from hdmi_channel_mapping[], causing wrong
channel maps to be shown.

Fix those issues.

Tested on Intel HDMI to correctly generate various channel maps, for
example 3,4,14,15,7,8,5,6 (instead of incorrect 3,4,8,7,5,6,14,0) for
standard 7.1 channel audio. (Note that the side and rear channels are
reported as RL/RR and RLC/RRC, respectively, as per the CEA-861
standard, instead of the more traditional SL/SR and RL/RR.)

Note that this only fixes the layouts that only contain traditional 7.1
speakers (2.0, 2.1, 4.0, 5.1, 7.1, etc.). E.g. the rear center of 6.1
is still being shown wrongly due to an issue with from_cea_slot()

BIOS can mark a pin as "no physical connection" if the port is used by an

such pins.

On Haswell, such a disconneted pin will keep muted and connected to the 1st
converter by default. But if the 1st convertor is assigned to a connected pin
for audio streaming. The muted disconnected pin can make the connected pin

MacBook 6,1 and 6,2 have a CS4208 codec instead of CS4206/CS4207 on
the former models.  Most of functions work fine as is, except for the
silent speaker output.  After debugging sessions, it turned out that
the machine needs to set GPIO 0 for the speaker amp.

This patch adds the basic support for CS4208 and the fixup for these
MacBooks.  Basically the codec works just with the generic parser.
For re-using the existing GPIO amp code and init/free callbacks, a few
places have been changed so that CS4206/4207-specific codes (errata,
etc) won't hit with CS4208.

When Gfx driver reconnects a port and transcoder, the pin amplifier will
be muted. To enable sound, the pin amp need to be unmuted.

This patch
- moves pin amp unmuting from stream preparing to hdmi_setup_audio_infoframe().
  So if port:transcoder reconnection happens during stream playback, the ELDV
  unsol event can stil trigger pin's amp unmuting when re-setting up audio
  info frame.

- remove reading pin amp status before unmuting for speed-up, since pin amp
  should always be unmuted.

- rename haswell_verify_pin_D0() to haswell_verify_D0(), since the convertor
  power state is also fixed here.

ASUS TX300 has a built-in speaker in the tablet part and in the dock
part, and the tablet speaker is supposed to be unused while the
machine is docked.  The current HD-audio driver, however, doesn't
support the dock speaker, partly because BIOS doesn't set up the pin
for the corresponding output.

But, not only the missing pin config, also the missing unsol event
handling is another issue.  Otherwise the automatic switching via
dock/undock won't work.

Through debugging sessions, we found out that the dock speaker pin is
NID 0x1b, and it generates an unsol event at docking/undocking, the
docking state can be inquired via the normal pin detection verb.
Also, it's turned out that GPIO 2 is needed as an amp.  So, all
materials are ready to cook.

This patch provides the basic dock speaker support with TX300:
- The dock speaker is turned on/off via "Dock Speaker" mixer mute.
- The dock speaker is automatically muted when docked.  This is
  independently from the mixer mute switch, just like the headphone
  auto-mute function.

The implementation is a bit tricky.  Since we want to handle it as a
secondary speaker, we set it up a pin as a speaker with a jack
detection.  Then, the fixup function registers the own unsol callback
for this pin because the standard automute can't handle the thing like
a "speaker jack".  In the own automute hook, we apply the mute of the
tablet speaker in addition by checking the dock state.

Also, the speaker control names are slightly shuffled because the
generic parser doesn't give good names but blindly assumes a bass
speaker as a secondary speaker.

When the transcoder:port mapping on Haswell HDMI/DP audio is changed
during the stream playback, the sound gets lost.  Typically this
problem is seen when the user switches the graphics mode from eDP+DP
to DP-only configuration, where CRTC 1 is used for DP in the former
while CRTC 0 is used for the latter.

The graphics controller notifies the change via the normal ELD update
procedure, so we get the intrinsic event.  For enabling the sound
again, the HDMI audio driver needs to reset the pin and set up the
audio infoframe again.

This patch achieves it by:
- keep the current status of channels and info frame setup in per_pin
  struct,
- check the reconnection in the intrinsic event handler,
- reset the pin and the re-invoke hdmi_setup_audio_infoframe()
  accordingly.

The hdmi_setup_audio_infoframe() function has been changed, too, so
that it can be invoked without passing the substream instance.

The patch is mostly based on the work by Mengdong Lin.

hdmi_channel_allocation() tries to find a HDMI channel allocation that
matches the number channels in the playback stream and contains only
speakers that the HDMI sink has reported as available via EDID. If no
such allocation is found, 0 (stereo audio) is used.

Using CA 0 causes the audio causes the sink to discard everything except
the first two channels (front left and front right).

However, the sink may be capable of receiving more channels than it has
speakers (and then perform downmix or discard the extra channels), in
which case it is preferable to use a CA that contains extra channels
than to use CA 0 which discards all the non-stereo channels.

Additionally, it seems that HBR (HD) passthrough output does not work on
Intel HDMI codecs when CA is set to 0 (possibly the codec zeroes
channels not present in CA). This happens with all receivers that report
a 5.1 speaker mask since a HBR stream is carried on 8 channels to the
codec.

Add a fallback in the CA selection so that the CA channel count at least
matches the stream channel count, even if the stream contains channels
not present in the sink speaker descriptor.

Thanks to GrimGriefer at OpenELEC forums for discovering that changing
the sink speaker mask allowed HBR output.

Add support for HDMI audio device on VGA cards that powerdown
to D3cold using non-standard ACPI/PCI infrastructure (optimus).

This does a couple of things to make it work:

a) add a set of power ops for the hdmi domain, and enables them
via vga_switcheroo when we are a switcheroo controlled card. This
just replaces the runtime resume operation so that when the card
is in D3cold the userspace pci config space access via sysfs,
the vga switcheroon runtime resume gets called first and it calls
the GPU resume callback before calling the sound card runtime
resume.

b) standard ACPI/PCI stacks won't put a device into D3cold without
an ACPI handle, but since the hdmi audio devices on gpus don't have
an ACPI handle, we need to manually force the device into D3cold
after suspend from the switcheroo path only.

c) don't try and do runtime s/r when the GPU is off.

d) call runtime suspend/resume during switcheroo suspend/resume
this is to make sure the runtime stack knows to try and resume
the hdmi audio device for pci config space access.

v2: fix incorrect runtime call suspend->resume.

v3: rework irq handler to avoid false irq when we are resuming
but haven't runtime resumed yet, don't bother trying D3cold,
it won't work, just set it manually ourselves, move runtime s/r
calls outside the main s/r hook. enable dnyamic pm properly by
dropping reference.

v4: put back irq handler check just wrap it with cap check
