It is unfortunate that we have these two types of bindings, one used by some of the legacy fbdev drivers and the other by DRM/KMS drivers. There isn't really much we can do about it, though, as far as I can see.
This panel is used with an fbdev driver, right?

I wasn't aware that they were any different. Where is the equivalent binding for DRM/KMS panels?
I guess one must have been merged first and the second one screwed up by not reusing the first one :(

Yes.
I don't know if I will be able to convert the AMBA CLCD driver from fbdev to DRM/KMS but I was hoping I would not have to change the DT to redescribe the same hardware for that, but now it sounds like that is a consequence...
