IMHO I'm not sure if this is applicable here, in this case the bridge
is transparent so it's not required another device node. For example,
I've an evaluation board, whre I connect in one side an HDMI input
signal an in the other side a DP monitor, the driver only configures
the chip and waits for different events (cable plug, cable unplug, etc
..)

Cheers,
Enric
