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.

Boris Brezillon (4):
the property parsing logic can be shared by all DRM
drivers.
A driver can now attach underscan properties to its connector through
the drm_connector_attach_underscan_properties() helper, and can
check/apply the underscan setup based on the
drm_connector_state->underscan fields.
Signed-off-by: B
Now that underscan props can be parsed by the core and assigned to
conn_state->underscan.xxx, we can rely on this implementation and get
rid of the nouveau-specific underscan props.

the property parsing logic can be shared by all DRM

A driver can now attach underscan properties to its connector through
the drm_connector_attach_underscan_properties() helper, and can
check/apply the underscan setup based on the
drm_connector_state->underscan fields.

The HVS spec recommends using PPF when the downscaling ratio is
between 2/3 and 1. Let's modify vc4_get_scaling_mode() to follow this
recommendation.
