Subject: [PATCH v7 0/3] drm/bridge_connector: implement OOB HPD handling
Note, numbering for this series starts from v5, since there were several
revisions for this patchset under a different series title ([1]).
USB altmodes code would send OOB notifications to the drm_connector
specified in the device tree. However as the MSM DP driver uses
drm_bridge_connector, there is no way to receive these event directly.
Implement a bridge between oob_hotplug_event and drm_bridge's
hpd_notify.
Merge strategy: since this series touches i915 code, it might make sense
to merge it through drm-intel.

Changes since v6:
- Fixed the fwnode refcount in drm/bridge-connector
Changes since v5:
- Fixed checkpatch warning in the first patch (noted by intel-gfx CI).
Changes since v4:
- Picked up the patchset
- Dropped msm-specific patches
- Changed drm_bridge_connector_oob_hotplug_event to call connector's HPD
callback directly, rather than going through the last bridge's
hpd_notify
- Added proper fwnode for the drm_bridge_connector
Bjorn Andersson (1):
drm: Add HPD state to drm_connector_oob_hotplug_event()
Dmitry Baryshkov (2):
drm/bridge_connector: stop filtering events in
drm_bridge_connector_hpd_cb()
drm/bridge_connector: implement oob_hotplug_event
