We will soon support devices other than phys on the mdio bus. Look at
a child's compatibility string to determine if it is a phy, before
registering a phy device.

These are logically MDIO operations, not phy operations, so move them
into the mdio header.

Not all devices attached to an MDIO bus are phys. So add an
mdio_device structure to represent the generic parts of an mdio
device, and place this structure into the phy_device.

Many Ethernet drivers contain the same netdev_info() print statement

The address of the device can be determined from the phydev structure,

Make it clear that mdiobus_scan () will only find devices which have a
vendor/product ID in registers 2 and 3. These are typically PHY
devices. Other sort of MDIO devices, such as switches, are not
expected to be found during the scan.
Similarly, __mdiobus_register(), which calls mdiobus_scan() wi
In preparation for moving some of the phy_device structure members,

The discussions about changing the way DSA probes switches resulted in
the wish to have switches attached to an MDIO bus to be represented as
an MDIO device. However the current code only supports PHYs on MDIO
busses. This patchset remedies this problem. It consists of a number
of cleanups, abstrac
Since we have a phydev, make use of it and the phy_read() function.
This will help with later refactoring.

The mdio_bus exports three attributes. However these are all phy
attributes, not generic mdio attributes. So move the attributes into

When the phy is connected, an info message is printed. If the netdev
it is attached to has not been registered yet, the name
'uninitialised' in the output. By registering the netdev first, then
connecting they phy, we can avoid this.
