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 Boris Brezillon (4): drm/connector: Add generic underscan properties drm/vc4: Take underscan setup into account when updating planes drm/vc4: Attach underscan props to the HDMI connector drm/nouveau: Switch to the generic underscan props drivers/gpu/drm/drm_atomic.c | 12 +++ drivers/gpu/drm/drm_connector.c | 127 ++++++++++++++++++++++++++++ drivers/gpu/drm/nouveau/nouveau_connector.c | 39 ++------- drivers/gpu/drm/nouveau/nouveau_connector.h | 9 -- drivers/gpu/drm/nouveau/nouveau_display.c | 14 --- drivers/gpu/drm/nouveau/nouveau_display.h | 3 - drivers/gpu/drm/nouveau/nv50_display.c | 17 ++-- drivers/gpu/drm/vc4/vc4_hdmi.c | 25 ++++++ drivers/gpu/drm/vc4/vc4_plane.c | 49 ++++++++++- include/drm/drm_connector.h | 80 ++++++++++++++++++ 10 files changed, 310 insertions(+), 65 deletions(-) -- 2.14.1
