BTW, I see that we check for the connector type in debugfs.

$ git grep DRM_MODE_CONNECTOR_DisplayPort -- drivers/gpu/drm/msm/dp/
drivers/gpu/drm/msm/dp/dp_debug.c:
DRM_MODE_CONNECTOR_DisplayPort)
drivers/gpu/drm/msm/dp/dp_debug.c:
DRM_MODE_CONNECTOR_DisplayPort)
drivers/gpu/drm/msm/dp/dp_debug.c:
DRM_MODE_CONNECTOR_DisplayPort)
drivers/gpu/drm/msm/dp/dp_debug.c:
DRM_MODE_CONNECTOR_DisplayPort)

So do those need to be updated to handle either connector type?
