Description
PI3WVR31313A has two passive output port1 and port2, one ac-
tive (DP to HDMI) output port3. Passive output ports support
DP1.2 at 5.4Gbps. Active port3 support HDMI1.4b at 3.4Gbps.
All three output ports support auto port priority selection. In-
put port accepts DP1.2 and DP++ signals associated with output
ports as described above.
