  "message": "Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.\n\nThis feature is useful when your board uses different mii buses for different\nphys and all (or a part) of these buses are implemented via bit-banging mode.\n\nThe driver requires that the following macros should be defined into the board\nconfiguration file:\n\nCONFIG_BITBANGMII       - Enable the miiphybb driver\nCONFIG_BITBANGMII_MULTI - Enable the multi bus support\n\nIf the CONFIG_BITBANGMII_MULTI is not defined, the board\u0027s config file needs\nto define at least the following macros:\n\nMII_INIT      - Generic code to enable the MII bus (optional)\nMDIO_DECLARE  - Declaration needed to access to the MDIO pin (optional)\nMDIO_ACTIVE   - Activate the MDIO pin as out pin\nMDIO_TRISTATE - Activate the MDIO pin as input/tristate pin\nMDIO_READ     - Read the MDIO pin\nMDIO(v)       - Write v on the MDIO pin\nMDC_DECLARE   - Declaration needed to access to the MDC pin (optional)\nMDC(v)        - Write v on the MDC pin\n\nThe previous macros make the driver compatible with the previous version\n(that didn\u0027t support the multi-bus).\n\nWhen the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill\nthe bb_miiphy_buses[] array with a record for each required bus and declare\nthe bb_miiphy_buses_num variable with the number of mii buses.\nThe record (struct bb_miiphy_bus) has the following fields/callbacks (see\nmiiphy.h for details):\n\nchar name[]            - The symbolic name that must be equal to the MII bus\n                         registered name\nint (*init)()          - Initialization function called at startup time (just\n                         before the Ethernet initialization)\nint (*mdio_active)()   - Activate the MDIO pin as output\nint (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin\nint (*set_mdio)()      - Write the MDIO pin\nint (*get_mdio)()      - Read the MDIO pin\nint (*set_mdc)()       - Write the MDC pin\nint (*delay)()         - Delay function\nvoid *priv             - Private data used by board specific code\n\nThe board code will look like:\n\nstruct bb_miiphy_bus bb_miiphy_buses[] \u003d {\n { .name \u003d miibus#1, .init \u003d b1_init, .mdio_active \u003d b1_mdio_active, ... },\n { .name \u003d miibus#2, .init \u003d b2_init, .mdio_active \u003d b2_mdio_active, ... },\n ...\nint bb_miiphy_buses_num \u003d sizeof(bb_miiphy_buses) /\n                          sizeof(bb_miiphy_buses[0]);\n\nSigned-off-by: Luigi \u0027Comio\u0027 Mantellini \u003cluigi.mantellini@idf-hit.com\u003e\nSigned-off-by: Ben Warren \u003cbiggerbadderben@gmail.com\u003e\n",
