39   ti,fiber-mode:
48        In fiber mode, auto-negotiation is disabled and the PHY can only work in
49        100base-fx (full and half duplex) modes.
51   rx-internal-delay-ps:
54        Setting this property to a non-zero number sets the RX internal delay
55        for the PHY.  The internal delay for the PHY is fixed to 3.5ns relative
58   tx-internal-delay-ps:
61        Setting this property to a non-zero number sets the TX internal delay
62        for the PHY.  The internal delay for the PHY is fixed to 3.5ns relative

78        of the logical level +1 for the MLT-3 encoded TX data.
