In the cover mail you write that this is a combination of the STDP4028
DP transmitter and STDP2690 DP/DP++ converter. So shouldn't this binding
comprise two device tree nodes, one with compatible "st,stdp4028", one
with "st,stdp2690", then?
Is the stdp2690 connected to the stdp4028's i2c master?

regards
Philipp
