-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
-
-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[] = {

+Bit-banged MII bus support
+==========================
+
+The miiphybb ( Bit-banged MII bus driver ) supports an arbitrary number of
+MII buses. This feature is useful when a driver 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 macro is defined in the board
+configuration file:
+
+* CONFIG_BITBANGMII - Enable the miiphybb driver
+
+The driver code needs to allocate a regular MDIO device using mdio_alloc()
+and assign .read and .write accessors which wrap bb_miiphy_read() and
+bb_miiphy_write() functions respectively. The bb_miiphy_read() and
+bb_miiphy_write() functions take a pointer to a callback structure,
+struct bb_miiphy_bus_ops. The struct bb_miiphy_bus_ops has the following
+fields/callbacks (see miiphy.h for details):
+
+.. code-block:: c
+
+    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
+
+The driver code will look like:
+
+.. code-block:: c
+
+    static const struct bb_miiphy_bus_ops ravb_bb_miiphy_bus_ops = {
+        .mdio_active      = ravb_bb_mdio_active,
+        .mdio_tristate    = ravb_bb_mdio_tristate,
+        .set_mdio         = ravb_bb_set_mdio,
+        .get_mdio         = ravb_bb_get_mdio,
+        .set_mdc          = ravb_bb_set_mdc,
+        .delay            = ravb_bb_delay,
+    };
+
+    static int ravb_bb_miiphy_read(struct mii_dev *miidev, int addr,
+                                   int devad, int reg)
+    {
+        return bb_miiphy_read(miidev, &ravb_bb_miiphy_bus_ops,
+                              addr, devad, reg);
+    }
