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:
42        DP83822 PHY only.
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:
53        DP83822 PHY only.
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:
60        DP83822 PHY only.
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
