dt-bindings: net: Add documentation for Half duplex support. In order to support half-duplex operation at 10M and 100M link speeds, the PHY collision detection signal (COL) should be routed to ICSSG GPIO pin (PRGx_PRU0/1_GPI10) so that firmware can detect collision signal and apply the CSMA/CD algorithm applicable for half duplex operation. A DT property, "ti,half-duplex-capable" is introduced for this purpose. If board has PHY COL pin conencted to PRGx_PRU1_GPIO10, this DT property can be added to eth node of ICSSG, MII port to support half duplex operation at that port.
