Hi all,

This patchset attempts to support multi-channel HDMI audio.

It contains two basic operations:

- setup the CA(channel-allcation) byte in the audio infoframe
- setup the converter channel to HDMI slot mapping

Please check the last two patches for the detailed descriptions:

	[PATCH 1/4] hda: make standalone hdmi_fill_audio_infoframe()                               
	[PATCH 2/4] hda: make global snd_print_channel_allocation()                       

	[PATCH 3/4] hda: HDMI channel allocations for audio infoframe                               
	[PATCH 4/4] hda: HDMI channel mapping cleanups                                               

The current implementation only does minimal works that can ensure the
multi-channel audio playing out. However the wrong speakers may be choosed, and
I really need more information/knowledge/instructions from you to get it right.

Thank you,
