That panel-dpi is omapdrm specific panel-dpi, but yes, Thierry should've
been included in the thread.

It's on the TODO list.

I took these panel-dpi patches as they were for an already existing
driver and looked trivial enough, but I haven't added new panel/encoder
drivers for a while. In fact, I've been holding out from upstreaming a
bunch of encoder/panel drivers from TI's kernel as they're omapdrm based.

Moving to DRM encoders and panels is a huge change, and probably
requires rewriting good part of omapdrm and omapdss drivers. And then
porting all the encoder and panel drivers to DRM.

So I'm not sure when I can start on that work, but even when I do, I
expect it to take a rather long time. But I know my life would be easier
after that change, so I very much like to make it happen.

 Tomi
