Shortly about the display components in the series, in the order of probable
public interest:

* Analog TV, DVI and HDMI Connectors represent a respective connector on the
   board. They don't do much, but they do mark the end of the video pipeline (from
   the board's pov), and they should also in the future offer ways to handle
   things like the +5V pin on DVI and HDMI connector and HPD pin.

* MIPI DPI panel and MIPI DSI CM panels represent bindings for simple panels
   using the respective video bus.

* Sony acx565akm is an SPI controlled panel using flatlink video bus.

* TFP410 is a DPI to DVI encoder.

* TPD12S015 is a HDMI companion chip, used on OMAP boards.

Tomi,

Out of curiosity, will there be DT nodes for pull-up resistors soon,
too? ;)

Honestly, TPD12S015 is a level shifter, there is nothing in it that
would justify a DT node nor a driver.

Above you already note, that connector nodes should offer HPD in the
future, but I guess the binding should represent that now already.
I will be a DT stub anyway, the corresponding video sink driver will
have to look it up.

Looking through the bindings for DVI and HDMI, I guess HPD gpio is
better kept in those nodes. From the relevant (DT) properties DVI and
HDMI connectors are in no way different.
