[alsa-devel] [PATCH v6 00/15] ASoC: hdac_hdmi: Add DP & notification support

[Subhransu S. Prusty]

This patch series adds DP audio and hotplug notification support.

In skylake platform the DP is on a different port which is not
enabled by default. A vendor widget is programmed to enable
playback on all ports. This also enables all the converters.

Codec Dais, widgets, graph are now created dynamically based on
the nodes enumerated, thus removing the hardcoding. Mux controls
are used to establish routing stream to a specific port.

For DP audio support, infoframe needs to be different. Based on
ELD queried we either pack HDMI or DP infoframe.

Also with this series, Jack notification support is added and
Jack event is reported to userspace as is done in case of legacy
driver.

Few fixes are added to check for possible memory leak,
reconfiguring register during resume from D3 etc.

The 8th patch is adding a small macro for getting connection type
in drm header. It is reviewed by drm folks, CCed them. Please
merge it through sound trees.

changes in v6:
	- Fixed some review comments
	- Fix afg node D3 state
