I like that you didn't include a "fb" suffix for this, the existing
ones are cargo culting from the previous fbdev driver to make existing
DTBs compatible with the DRM driver.

I've been thinking if I should post a patch to compatible strings
without the "fb" and mark the current ones as deprecated...
