No argument here.

No, I don't think so. It's a end of line for it, I believe. From my
personal point of view the main goal is to fill the last gap between DT
and non-DT support on one of the Versatile Express boards - CLCD works
fine when booted with ATAGs, doesn't work when booted with DT. It looks
bad.

I would hope so, yes. VE display pipeline is quite complex (more than I
would hope ;-) so to implement KMS in a proper way (with hotplugging,
bells and whistles) it will have to know more than now. But it's out of
scope for me.
