[alsa-devel] [PATCH] hda: Advanced power management for codecs.

[Matthew Ranostay]

Added support for advanced power management features in new IDT codecs. 
Inactive ADCs and DACs are changed to D3 mode when not in playback or 
capture, also inactive line-out/headphone ports are disabled when jack 
detect does not sense a connection.
