If you mean the panel drivers, then I disagree. They are currently OMAP
specific, but they are designed so that making them generic shouldn't be
too difficult. It's been my aim for a long time already to make the
panel drivers generic, but I've never had time and it's never been quite
clear to me what would be the best way to do that.

The core DSS driver is OMAP specific, and while the DSS IP could in
theory be used in some other platform, that is not currently the case
and I wouldn't want to needlessly start abstracting things for just the
sake of abstracting.
