AIUI, we're not taking new FB drivers. This should be a DRM
driver
instead.

Yes - clone one of the dumb DRM drivers, or if you've got any
little bits
of acceleration (even rolling the display) then it's possibly worth
accelerating for text mode.

+- max-width: The width of the framebuffer in pixels.
+- max-height: The height of the framebuffer in pixels.
+- bits-per-color: only "8" is currently supported

These are not h/w properties.

How are the max ones not hardware properties ?

Because the way they are used is setting the mode, not some check of
the max when the mode is set. If this is synthesized for only one
size, then that would be different, but we have bindings for modes.

Currently the idea is to just synthesize the display to just 1920 x
1080. Therefore we came to a conclusion that it should be part of the
HW properties.
