372 Value type: <stringlist>
373 Definition: A standard property.
374 Must include "fsl,fman-mdio" for 1 Gb/s MDIO from FMan v2.
375 Must include "fsl,fman-xmdio" for 10 Gb/s MDIO from FMan v2.
376 Must include "fsl,fman-memac-mdio" for 1/10 Gb/s MDIO from
381 Value type: <prop-encoded-array>
382 Definition: A standard property.
387 Definition: Specifies the external MDIO bus clock speed to
388 be used, if different from the standard 2.5 MHz.
389 This may be due to the standard speed being unsupported (e.g.
390 due to a hardware problem), or to advertise that all relevant
391 components in the system support a faster speed.
394 Usage: required for external MDIO
395 Value type: <prop-encoded-array>
396 Definition: Event interrupt of external MDIO controller.
398 - fsl,fman-internal-mdio
399 Usage: required for internal MDIO
401 Definition: Fman has internal MDIO for internal PCS(Physical
402 Coding Sublayer) PHYs and external MDIO for external PHYs.
403 The settings and programming routines for internal/external
404 MDIO are different. Must be included for internal MDIO.
406 - fsl,erratum-a011043
408 Value type: <boolean>
409 Definition: Indicates the presence of the A011043 erratum
410 describing that the MDIO_CFG[MDIO_RD_ER] bit may be falsely
411 set when reading internal PCS registers. MDIO reads to
412 internal PCS registers may result in having the
413 MDIO_CFG[MDIO_RD_ER] bit set, even when there is no error and
414 read data (MDIO_DATA[MDIO_DATA]) is correct.
415 Software may get false read error when reading internal
416 PCS registers through MDIO. As a workaround, all internal
417 MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.
419 For internal PHY device on internal mdio bus, a PHY node should be created.
420 See the definition of the PHY node in booting-without-of.txt for an
421 example of how to define a PHY (Internal PHY has no interrupt line).
422 - For "fsl,fman-mdio" compatible internal mdio bus, the PHY is TBI PHY.
423 - For "fsl,fman-memac-mdio" compatible internal mdio bus, the PHY is PCS PHY,
424 PCS PHY addr must be '0'.
428 Example for FMan v2 external MDIO:
431 compatible = "fsl,fman-xmdio";
432 reg = <0xf1000 0x1000>;
433 interrupts = <101 2 0 0>;
