Subject: [RFC PATCH 0/4] drm/msm/dp: implement HPD notifications handling
Date: Fri, 29 Apr 2022 22:29:24 +0300 [thread overview]
Message-ID: <20220429192928.3697407-1-dmitry.baryshkov@linaro.org> (raw)
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
Bjorn Andersson (2):
drm: Add HPD state to drm_connector_oob_hotplug_event()
drm/msm/dp: Implement hpd_notify()
Dmitry Baryshkov (2):
drm/bridge_connector: stop filtering events in
drm_bridge_connector_hpd_cb()
drm/bridge_connector: implement oob_hotplug_event
