DRM_MODE_REFLECT_X and DRM_MODE_REFLECT_Y meaning seems a bit unclear
to me, so try to clarify that with a bit of ascii graphics.

I think the above won't render correctly in sphinx. I think you need some
fixed-block quoting. Please run

$ make htmldocs

and check the output. With that addressed:

One small problem here this file is not included in the htmldoc
generation and no comment in here is marked to be included in html
documentation.

Hah, I guess my review was sub-par. And with that I realized we have have
this prop fairly well documented already, but it's hidden in
drm_plane_create_rotation_property(). Plus linked from

https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#plane-composition-properties

Might be better to move everything there, and just leave a hint here?

I agree, it makes perfectly sense to move it to
drm_plane_create_rotation_property and just point to that here.

I will do that in v2.
