It's fairly common to have one LCD controller appear in many different devices (because its part of the CPU) and have the same display, yet need different timing.
This was something that I was worried about -- it seems like this sort
of thing would negate any benefit from building a database of panels for
general use.
Perhaps it would be posible to build a database of panels as described
in their datasheets. Boards which have a CPLD could perhaps define a
per-board fixup function, since they know the sync lines are inverted or
whatever.
I'm not sure though -- my experience is with our board which has a
PXA255 and no CPLD messing with the display controller stuff. I'm wary
of coming up with a solution which is only useful to me and noone
else...
