-This patch rewrites the miiphybb ( Bit-banged MII bus driver ) in order to
-support an arbitrary number of mii buses. This feature is useful when your
-board uses different mii buses for different phys and all (or a part) of these
-buses are implemented via bit-banging mode.
-
-The driver requires that the following macros should be defined into the board
-configuration file:
-
-CONFIG_BITBANGMII - Enable the miiphybb driver
-CONFIG_BITBANGMII_MULTI - Enable the multi bus support
-
-If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
-to define at least the following macros:
-
-MII_INIT - Generic code to enable the MII bus (optional)
-MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
-MDIO_ACTIVE - Activate the MDIO pin as out pin
-MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
-MDIO_READ - Read the MDIO pin
-MDIO(v) - Write v on the MDIO pin
-MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
-MDC(v) - Write v on the MDC pin
-
-The previous macros make the driver compatible with the previous version
-(that didn't support the multi-bus).
-
-When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
-the bb_miiphy_buses[] array with a record for each required bus and declare
-the bb_miiphy_buses_num variable with the number of mii buses.
-The record (struct bb_miiphy_bus) has the following fields/callbacks (see
-miiphy.h for details):
-
-char name[] - The symbolic name that must be equal to the MII bus
- registered name
-int (*init)() - Initialization function called at startup time (just
- before the Ethernet initialization)
-int (*mdio_active)() - Activate the MDIO pin as output
-int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
-int (*set_mdio)() - Write the MDIO pin
-int (*get_mdio)() - Read the MDIO pin
-int (*set_mdc)() - Write the MDC pin
-int (*delay)() - Delay function
-void *priv - Private data used by board specific code
-
-The board code will look like:
-
-struct bb_miiphy_bus bb_miiphy_buses[] = {
- { .name = "miibus#1", .init = b1_init, .mdio_active = b1_mdio_active, ... },
- { .name = "miibus#2", .init = b2_init, .mdio_active = b2_mdio_active, ... },
- ...
-};
-int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
- sizeof(bb_miiphy_buses[0]);
