Hello,
This is an attempt at providing generic support for underscan connector props. We already have 3 drivers defining the same underscan, underscan vborder and underscan hborder properties (amd, radeon and nouveau) and I am about to add a new one, hence my proposal to put the prop parsing code in the core and add ->underscan fields to drm_connector_state.
In this v2, I also converted the nouveau driver to the generic approach. The amdgpu and radeon ones can't be converted since they're still not converted to the atomic interface.
Regards,
Boris
