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 :(
> This panel is used with an fbdev driver, right?
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...
