Note, numbering for this series starts from v5, since there were several

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 all three patches through drm-intel.

Dear drm-misc and drm-intel maintainers. Since the merge window has ended and the trees are fully open for the patches, I'd like to massage this patch series. We have R-B on all three patches. Heikki has acked the first patch, so it seems to be fine from the i915 point of view.

Is it fine to be merged via drm-misc? Would you like to pick it up into drm-intel?



[1] https://patchwork.freedesktop.org/series/103449/

Changes since v6:
- Rebased on top of linux-next. Fixed the freshly added
   new drm_connector_oob_hotplug_event() call.

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

   drm/bridge_connector: stop filtering events in
     drm_bridge_connector_hpd_cb()
