Adding kuogee to keep him in the loop to review/test these.
Thanks

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
and use it to deliver altmode messages to the MSM DP driver.
Note, I left the original 'bool connected' field to be used by the
notifiers. However I think that it should be replaced in favour of using
the dp->hpd_state properly.
Changes since RFC v1:
- Incorporated old patch dropping old usbpd code. Most of it remained
unused.
Bjorn Andersson (2):
drm: Add HPD state to drm_connector_oob_hotplug_event()
drm/msm/dp: Implement hpd_notify()
Dmitry Baryshkov (3):
drm/bridge_connector: stop filtering events in
drm_bridge_connector_hpd_cb()
drm/bridge_connector: implement oob_hotplug_event
drm/msm/dp: remove most of usbpd-related remains
