Level shifter FET and 5V PU resistor shall be placed
between the Module and the HDMI connector.
Stronger pull-up is demanded to the carrier board.
The pull-ups may be part of an integrated HDMI ESD
protection and control-line level shift device, such as the
Texas Instruments TPD12S016.
If discrete Carrier pull-ups are used, the value depends on
the individual carrier board implementation.
