62 amlogic,tx-delay-ns:
65 The internal RGMII TX clock delay (provided by this driver) in
66 nanoseconds. Allowed values are 0ns, 2ns, 4ns, 6ns.
67 When phy-mode is set to "rgmii" then the TX delay should be
68 explicitly configured. When not configured a fallback of 2ns is
69 used. When the phy-mode is set to either "rgmii-id" or "rgmii-txid"
70 the TX clock delay is already provided by the PHY. In that case
71 this property should be set to 0ns (which disables the TX clock
72 delay in the MAC to prevent the clock from going off because both
73 PHY and MAC are adding a delay).
74 Any configuration is ignored when the phy-mode is set to "rmii".

78 - 0

82 The internal RGMII RX clock delay (provided by this IP block) in
83 nanoseconds. When phy-mode is set to "rgmii" then the RX delay
84 should be explicitly configured. When the phy-mode is set to
85 either "rgmii-id" or "rgmii-rxid" the RX clock delay is already
87 phy-mode is set to "rmii".
