[PATCH v2 0/4] drm/connector: Provide generic support for underscan

[Boris Brezillon]

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
