From: Libin Yang <libin.yang at linux.intel.com>

The patches are trying to support dynamically binding PCM to pin
in HDMI/DP audio.

The pin will not bind to any PCM if there is not monitor connected.
When there is a monitor connected to the port (pin), driver will
try to find a proper PCM to assign to the port and setup the pin
if necessary.

Libin Yang (5):
  ALSA: hda - hdmi playback without monitor in dynamic pcm bind mode
  ALSA: hda - hdmi operate spdif based on pcm
  ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug
  ALSA: hda - add in_use flag in hda_pcm
  ALSA: hda - hdmi setup pin when monitor hotplug in pcm dynamic
    assignment mode
