[PATCH v2 0/7] drm/msm/dp: Support for external displays

[Bjorn Andersson]

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):
