similar to: [PATCH 3/6] drm/i915: Leave intel_conn->mst_port set, use mst_port_gone instead

Currently we set intel_connector->mst_port to NULL to signify that the MST port has been removed from the system so that we can prevent further action on the port such as connector probes, mode probing, etc. However, we're going to need access to intel_connector->mst_port in order to fixup ->best_encoder() so that it can always return the correct encoder for an MST port to prevent

Next version of https://patchwork.freedesktop.org/series/49878/ . No changes, except that these patches are against master so hopefully intel's CI doesn't get confused this time.

Next version of https://patchwork.freedesktop.org/series/49877/ This fixes some rather silly bugs regarding DPMS On->Off changes failing for connectors which were just recently destroyed.

Next version of https://patchwork.freedesktop.org/series/49878/ Still no functional changes, just removing a duplicate s-b to make CI happy.

Currently, i915 appears to rely on blocking modesets on no-longer-present MSTB ports by simply returning NULL for ->best_encoder(), which in turn causes any new atomic commits that don't disable the CRTC to fail. This is wrong however, since we still want to allow userspace to disable CRTCs on no-longer-present MSTB ports by changing the DPMS state to off and this still requires that we

Some notebook systems provide the EDID for the internal panel via the _DDC method in ACPI, instead of or in addition to providing the EDID via DDC on LVDS/eDP. Add a DRM helper to search for an ACP _DDC method under the ACPI namespace for each VGA/3D controller, and return the first EDID successfully retrieved via _DDC. Update the i915, nouveau, and radeon DRM-KMS drivers to fall back to

Currently the way that we prevent userspace from performing new modesets on MST connectors that have just been destroyed is rather broken. There's nothing in the actual DRM DP MST topology helpers that checks whether or not a connector still exists, instead each DRM driver does this on it's own, usually by returning NULL from the best_encoder callback which in turn, causes the atomic

This is the series I've been working on for a while now to get all of the atomic DRM drivers in the tree to use the atomic MST helpers, and to make the atomic MST helpers actually idempotent. Turns out it's a lot more difficult to do that without also fixing how port and branch device refcounting works so that it actually makes sense, since the current upstream implementation requires a

So that the ports stay around until we've destroyed the connectors, in order to ensure that we don't pass an invalid pointer to any MST helpers once we introduce the new MST VCPI helpers.

This is the next version of my patch series for teaching DRM how to automatically create debugfs nodes for drivers with MST topologies. This was originally intended just for nouveau, but has since been expanded to all DRM drivers. Changes since previous version: - Fix documentation error that got noticed by the kbuild bot in "drm/dp_mst: Pass entire connector to
