[PATCH 0/3] drm/connector: Provide generic support for underscan

[Boris Brezillon <boris.brezillon-LDxbnhwyfcJBDgjK7y7TUQ@public.gmane.org>]

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.

Note that I use this new infrastructure to support underscan in VC4
(path 2 and 3) but did not patch existing drivers yet, mainly because I
don't want to do this work before making sure I got the generic bits
right.

Regards,

Boris
