Each hardware port is assigned a 4KB, port-specific page in the FMan hardware port memory region (which is part of the FMan memory map). The first 4 KB in the FMan hardware ports memory region is used for what are called common registers. The subsequent 63 4KB pages are allocated to the hardware ports. The page of a specific port is determined by the cell-index. - reg Usage: required Value type: Definition: There is one reg region describing the port configuration registers. - fsl,fman-10g-port Usage: optional Value type: boolean Definition: The default port rate is 1G.

PROPERTIES - compatible Usage: required Value type: Definition: A standard property. Must include "fsl,fman-mdio" for 1 Gb/s MDIO from FMan v2. Must include "fsl,fman-xmdio" for 10 Gb/s MDIO from FMan v2. Must include "fsl,fman-memac-mdio" for 1/10 Gb/s MDIO from FMan v3. - reg Usage: required Value type: Definition: A standard property. - bus-frequency Usage: optional Value type: Definition: Specifies the external MDIO bus clock speed to be used, if different from the standard 2.5 MHz. This may be due to the standard speed being unsupported (e.g. due to a hardware problem), or to advertise that all relevant components in the system support a faster speed. - interrupts Usage: required for external MDIO Value type: Definition: Event interrupt of external MDIO controller. - fsl,fman-internal-mdio Usage: required for internal MDIO Value type: boolean Definition: Fman has internal MDIO for internal PCS(Physical Coding Sublayer) PHYs and external MDIO for external PHYs. The settings and programming routines for internal/external MDIO are different. Must be included for internal MDIO. - fsl,erratum-a011043 Usage: optional Value type: Definition: Indicates the presence of the A011043 erratum describing that the MDIO_CFG[MDIO_RD_ER] bit may be falsely set when reading internal PCS registers. MDIO reads to internal PCS registers may result in having the MDIO_CFG[MDIO_RD_ER] bit set, even when there is no error and read data (MDIO_DATA[MDIO_DATA]) is correct. Software may get false read error when reading internal PCS registers through MDIO. As a workaround, all internal MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit. For internal PHY device on internal mdio bus, a PHY node should be created. See the definition of the PHY node in booting-without-of.txt for an example of how to define a PHY (Internal PHY has no interrupt line). - For "fsl,fman-mdio" compatible internal mdio bus, the PHY is TBI PHY. - For "fsl,fman-memac-mdio" compatible internal mdio bus, the PHY is PCS PHY, PCS PHY addr must be '0'.
