This needs a better explanation.  We know that it's used on ARMs
reference boards.  Which other platforms will be making use of this
driver?  Do these other boards implement the same interface, including
the presence of the interrupt?

I'd need to re-read the specs, but I think that the interface this
driver uses is provided by ARMs FPGA rather than the LCD module itself,
and re-use of this driver would need that IP to be implemented elsewhere.
