30   ti,link-loss-low:
33        DP83822 PHY in Fiber mode only.
36        This property is only applicable if the fiber mode support is strapped
39   ti,fiber-mode:
43        If present the DP83822 PHY is configured to operate in fiber mode
44        Fiber mode support can also be strapped. If the strap pin is not set
46        If the fiber mode is not strapped then signal detection for the PHY
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
58   tx-internal-delay-ps:
61        Setting this property to a non-zero number sets the TX internal delay
65   ti,cfg-dac-minus-one-bp:
69        of the logical level -1 for the MLT-3 encoded TX data.
74   ti,cfg-dac-plus-one-bp:
78        of the logical level +1 for the MLT-3 encoded TX data.
83   ti,rmii-mode:
85        If present, select the RMII operation mode. Two modes are
87          - RMII master, where the PHY outputs a 50MHz reference clock which can
89          - RMII slave, where the PHY expects a 50MHz reference clock input
91        The RMII operation mode can also be configured by its straps.
