No, not quite just the compatible are different as the first and last
panel feature capacitive touch while the middle one is resistive and
the first two panels are parallel RGB ones while the last one is an
LVDS panel.

We have recently introduced panel-simple.yaml.
This is for dumb panels - where some of your panels could be candidates.
Please see the file in drm-misc-next, which is also where we will apply
you patch in the end.
So base the patch on drm-misc-next so we do not get conflicts when applying.
