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