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. > or drm driver support common panels/encoders? 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.
