I've never encountered this before, what does it do ?

Maybe
title: LVDS Display Panel Common Properties
or do you foresee this being useful for non-panel LBDS sinks too ? In
that case the title is fine, but the file could be moved in the parent
directory.
I'm also wondering what we should do with the data-mapping and
data-mirror properties. For an LVDS panel they're fine at the device
level, but for an LVDS sink, they may be better placed at the port or
endpoint level.
