The ADV7123 is a transparent VGA DAC. Unlike dumb VGA DACs it can be
controlled through a power save pin, and requires a power supply.
However, on most boards where the device is used neither the power save
signal nor the power supply are controllable.
To avoid developing a separate device-specific driver add an
"adi,adv7123" compatible entry to the dumb-vga-dac driver. This will
allow supporting most ADV7123-based boards easily, while allowing future
development of an adv7123 driver when needed without breaking backward
compatibility.
Shouldn't we have a DT binding doc for ADV7123, even if it's sharing
the dumb vga driver for now?

Same query for the Thine LVDS encoder.
Documentation/devicetree/bindings/display/bridge/thine,thc63lvdm83d.txt
Cool, didn't know these already existed :)
Thanks,
Archit
