The reason I decided to expose the device as a drm_bridge is because
there was several discussions about merging drm_bridge and
drm_encoder_slave, and IIRC, the proposal was to move to the drm_bridge
approach.

Another reason I've chosen to go for the drm_bridge solution is because
I wanted to avoid as much as possible the development of a new glue for
each new encoder bridge type (HDMI/DVI, DP, ...), and, AFAICT drm_bridge
allow that, while it's a bit more complicated with drm_encoder_slave.

Yes, I'll try to have a look.

Thanks,
