Add the Microtips Technology USA's MF-101HIEBCAF0 10.1"[0] panel,
MF-103HIEB0GA0 10.25"[1] panel, and Lincoln Technology Solutions'
LCD185-101CT 10.1"[2] panel.

Thes are all dual-lvds panels.

This one mentions some controls in '3. PIN DESCRIPTION' which
don't comply with this binding, like RL, TB, STBYB and RESET.
Note this binding only allows compatible, ports, backlight,
enable-gpios and power-supply properties, nothing more.

Regards,
Liu Ying

Maybe the internal module _can_ support these control options but the
actual panel hardware does not expose any of these controls on its
connector pin-out, and hence has no possibility for additional SW
control. Even for the usage, the device-tree node for the panel only has
"compatible" and "ports" properties defined.

The panel is being used within the confines of a simple panel.

Regards
Aradhya

If somehow some modules with those panels would need more control lines,
we'll simply move them out of simple panel bindings & drivers if
required.

Those are perfectly fine as is, we don't want useless description and dead code.

At least, power-supply is required by this binding doc.

It would be better to specify module vendor and panel type in
the compatible property instead of using the generic one in this
binding doc.

If TI is the module vendor, it could be something like "ti,panel-type-x".
See ili9881c based panel "bananapi,lhr050h41" as an example.
