But why? We already have DRM drivers for some of these devices.

No, we do not (only a few are available).

Sorry, I missed your word 'some'. Some == almost none from the list (I
don't remember exact numbers but something like 2 out of 10 are
supported by tiny DRM and see about interfaces).

Could we get an exact list?

The list AFAICT is the following. I'm not familiar with these so please
feel free to correct anything I got wrong here.

I've marked with '?' if found references to the device supported by the
fbdev driver in a DRM driver, but it's not clear if support the same HW.
