[PATCH 0/7] drm/msm/dp: Support for external displays
From: Bjorn Andersson
Date: Tue Aug 09 2022 - 23:47:47 EST
Introduce support for DisplayPort on SDM845 and SC8280XP, followed by
introduction of drm_bridge based HPD handling.
The version of these patches are restarted, as the previous
drm_connector_oob_hotplug_event()-based approach was abandoned and this only
barely resembles that effort.
In this effort the HPD handling is based on the reliance of the hpd_notify()
being invoked by a downstream (next_bridge) drm_bridge implementation, such as
the standard display-connector, or a something like an USB Type-C controller
implementation.
Bjorn Andersson (7):
dt-bindings: msm/dp: Add SDM845 and SC8280XP compatibles
drm/msm/dp: Stop using DP id as index in desc
drm/msm/dp: Add DP and EDP compatibles for SC8280XP
drm/msm/dp: Add SDM845 DisplayPort instance
drm/msm/dp: Implement hpd_notify()
drm/msm/dp: Don't enable HPD interrupts for edp
drm/msm/dp: HPD handling relates to next_bridge
