Hi all,

This is second series of the HDA HDMI patches. This attempts to add HDA
based HDMI driver and uses i915 component framework to interact with
display for power up/down. The communication to codec is over HDA link

If at all we need a change in interface, we can i915 interface which can be
made transparent to users

Due to dependency on already merged patches in ALSA tree, it would be best
if this get merged thru ALSA tree

Changes in v2:
- remove infoframe open code and use video one
- add pm on/off i915 triggers
- add ext_dma_params struct

  ASoC: hdac_hdmi: Add PM support for HDMI
  ASoC: hdac_hdmi: Add hdac hdmi dai ops
