Add a binding document for it.

+The ANX6345 is an ultra-low power Full-HD eDP transmitter designed for +portable devices.
+Required properties:
- compatible : "analogix,anx6345"
- reg : I2C address of the device
- reset-gpios : Which GPIO to use for reset
+Optional properties:
- dvdd12-supply : Regulator for 1.2V digital core
power.
- dvdd25-supply : Regulator for 2.5V digital core
power.
Shouldn't these to supplies be mandatory ?
Yes they should.
- panel-supply : Regulator for the power of
the panel.
Shouldn't the panel supply for specified in the DT node of the panel ?
However, eDP panel can be probed, may vary on the same device,
and
we don't have a generic binding for it...
Shouldn't we fix that ? :-)
Maybe we should create a connector binding instead of a panel
binding?
There's not any such thing as a standard eDP connector, is there? Otherwise, that's just creating a generic panel binding in disguise. Maybe if eDP interface is standardized enough in terms of power control, control lines, EDID at least sometimes present, etc., then we could
eDP has the same display signal set with DP, including AUX which carries DPCD and EDID (if present).
But I don't know whether other lines are standardized, including power, backlight, etc.
have some sort of generic eDP panel/connector binding.
