[PATCH v1 1/2] dt-bindings: display: panel: document Atrix 4G and Droid X2 DSI panel
Posted by Svyatoslav Ryhel 2 weeks ago 
Atrix 4G and Droid X2 use the same 540x960 DSI video mode panel. Exact
panel vendor and model are unknown hence generic compatible is used based
on board name it is used with.

What's a "mot" panel? If that's short for motorola, wouldn't it be
better to conjure up something at least more specific to these
particular users? The commit message has some info, but I still dunno
where "mot" comes from.
Seems okay otherwise..

"Mot" is how motorola called tegra20 board files which were base for
Atrix 4G and Droid X2 in their downstream sources, specifically
board-mot-panel.c. Since both devices use the same panel I used board
name. Hopefully, at come point I will be able to name it properly.

I have device trees for both devices prepared and I will submit them shortly.

Can you put this explanation in the commit message please? Without being
familiar with the platform, it's nigh impossible to know how "mot"
relates to Atrix 4G or Droid X2.

Sure, if v2 is required, I will update commit message.
