411 be used, if different from the standard 2.5 MHz.

425 Coding Sublayer) PHYs and external MDIO for external PHYs.
426 The settings and programming routines for internal/external
427 MDIO are different. Must be included for internal MDIO.
429 For internal PHY device on internal mdio bus, a PHY node should be created.
430 See the definition of the PHY node in booting-without-of.txt for an
431 example of how to define a PHY (Internal PHY has no interrupt line).
432 - For "fsl,fman-mdio" compatible internal mdio bus, the PHY is TBI PHY.
433 - For "fsl,fman-memac-mdio" compatible internal mdio bus, the PHY is PCS PHY,
434 PCS PHY addr must be '0'.
