[PATCHv3 0/3] hdmi: add unpack and logging functions

[Hans Verkuil]

This patch series adds new HDMI 2.0/CEA-861-F defines to hdmi.h and
adds unpacking and logging functions to hdmi.c. It also uses those
in the V4L2 adv7842 driver (and they will be used in other HDMI drivers
once this functionality is merged).

Changes since v2:
- Applied most comments from Thierry's review
- Renamed HDMI_AUDIO_CODING_TYPE_EXT_STREAM as per Thierry's suggestion.

Thierry, if this OK, then please give your Ack and I'll post a pull
request for 3.20 for the media git tree.

Regards,

	Hans
