Gracious ping regarding this series. It went for two weeks w/o review.
Few additional points 'pro':
- It makes it possible to handle hpd enablement in cases where the
driver uses a mixture of drm_bridge_connector and old connectors (msm)
- It makes it possible for other connectors to also implement dynamic
hpd enablement/disablement in a standard way
