Just a note: there is no toppoly->tpo change for *this* panel and
Pandora board. Just omapdss removal.

The GTA04 needs a toppoly->tpo change but no omapdss, removal.

So they solve different problems and are independent of each other.

GTA04: change vendor string
Pandora: remove omapdss, prefix

BR and thanks,
