ÎÎSupport Type 2 cable ID register
Description
PI3WVR31212A has one passive output port1, one active (DP to
HDMI) output port2. Passive output supports DP1.2 at 5.4Gbps
in I2C mode. Active port2 supports HDMI1.4b at 3.4Gbps.All
two output ports support auto port priority selection. Input port
accepts DP1.2 and DP++ signals associated with output ports as
described above.
