Yes. It does give me a few more gray hairs, though =). It'd be so much easier to have all related changes in one clean patch series. >> Note about board files: I only convert a few board files here for example.

To make the DSS work properly after this device model change, we also need to solve the problem related to multiple display devices on the same video bus. Did the approach I suggested in http://permalink.gmane.org/gmane.linux.ports.arm.omap/96039 look ok? Overo is the most complex one, I think the rest of the boards that require changes have just LCD and DVI that conflict. But it still means we'll have that kind of choice Kconfig option for all those boards. Tomi
