559059b27f ALSA: hda: add IbexPeak/Clarkdale HDMI model with static cvt/pin number
The new IbexPeak HDMI codec has 3 pin nodes and 2 converter nodes.
Here we assume only the first ones will be used.

87a8c3702e ALSA: hda - Add better Intel IbexPeak platform support
Here are the new sound enabling patches for IbexPeak.

Summary of tested features:

  - playback
    - Front Headphone: OK
    - 8 channel audio: Front/Rear/CLFE/Side all OK

  - recording
    - Front Mic/Rear Mic: both OK
      (front/rear/line mics are selectable in the "Input source" alsamixer control)
    - Line In: not working
      (in 6ch mode, its amp/mute, direction and route all looks fine,
       so I'm a little puzzled)
      (hopefully no one will care this feature)

  - digital SPDIF input/output: not tested (no equipment)

606c0cee69 ALSA: hda - enable HDMI audio pin out at module loading time
We found that enabling/disabling HDMI audio pin out at stream start/stop
time will kill the leading 500ms or so sound samples. Avoid this by enabling
pin out once and for ever at module loading time.

The leading ~500ms audio samples will still be lost when switching from
X-channel playback to Y-channel playback where X != Y. However there's no
much we can do about it: the audio infoframe has to change and it looks like
either G45 or YAMAHA requires some time to switch the configuration.

a1667e4eea ALSA: hda - allow multi-channel HDMI audio playback when ELD is not present
The YAMAHA AV-X1800 requires audio infoframe to include speaker-channel
mapping to play >2 channel HDMI audio. In theory that mapping should be
derived from its speaker configurations contained in its ELD. However we
currently cannot get ELD in console before the KMS functionalities are ready.
This is a more or less general issue at least in the near future. As a
workaround, we propose to allow playback of mult-channel audio when ELD
is not available.

1289e9e8b4 ALSA: hda - Modularize HD-audio driver
Split the monolithc HD-audio driver into several pieces:
 - snd-hda-intel   HD-audio PCI controller driver; loaded via udev
 - snd-hda-codec   HD-audio codec bus driver
 - snd-hda-codec-* Specific HD-audio codec drivers

When built as modules, snd-hda-codec (that is invoked by snd-hda-intel)
looks up the codec vendor ID and loads the corresponding codec module
automatically via request_module().

When built in a kernel, each codec drivers are statically hooked up
before probing the PCI.

This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module
information for each driver, and driver-linking codes between
codec-bus and codec drivers.

TODO:
  - Avoid EXPORT_SYMBOL*() when built-in kernel
  - Restore __devinit appropriately depending on the condition

698544de8a ALSA: hda: HDMI channel allocations for audio infoframe
To play a 3+ channels LPCM/DSD stream via HDMI,

	- HDMI sink must tell HDMI source about its speaker placements
	  (via ELD, speaker-allocation field)
	- HDMI source must tell the HDMI sink about channel allocation
	  (via audio infoframe, channel-allocation field)

(related docs: HDMI 1.3a spec section 7.4, CEA-861-D section 7.5.3 and 6.6)

This patch attempts to set the CA(channel-allocation) byte in the audio infoframe
according to
	- the number of channels in the current stream
	- the speakers attached to the HDMI sink

A channel_allocations[] line must meet the following two criteria to be
considered as a valid candidate for CA:
	1) its number of allocated channels = substream->runtime->channels
	2) its speakers are a subset of the available ones on the sink side

If there are multiple candidates, the first one is selected.  This simple
policy shall cheat the sink into playing music, but may direct data to the
wrong speakers.

5f1e71b1cc ALSA: ELD proc interface for HDMI sinks
Create /proc/asound/card<card_no>/eld#<codec_no> to reflect the audio
configurations and capabilities of the attached HDMI sink.

Some notes:

- Shall we show an empty file if the ELD content is not valid?
  Well it's not that simple. There could be partially populated ELD,
  and there may be malformed ELD provided by buggy drivers/monitors.
  So expose ELD as it is.

- The ELD retrieval routines rely on the Intel HDA interface,
  others are/could be universal and independent ones.

- How do we name the proc file?
  If there are going to be two HDMI pins per codec, then the current naming
  scheme (eld#<codec no>) will fail. Luckily the user space dependencies should
  be minimal, so it would be trivial to do the rename if that happens.

- The ELD proc file content is designed to be easy for scripts and human reading.
  Its lines all have the pattern:
	  <item_name>\t[\t]*<item_value>
  where <item_name> is a keyword in c language, while <item_value> could be any
  contents, including white spaces. <item_value> could also be a null value.

Reorder HDMI audio enabling sequence so that
	1) the sink knows about the coming audio stream
	2) unmute
	3) start transferring audio samples

The theory is that in the path A=>B=>C, we first make C ready, and then
enable B, and lastly allow A to send audio samples.
