net: phy: Allow pre-declaration of MDIO devices

2017-02-07T15:51:46+00:00

Allow board support code to collect pre-declarations for MDIO devices by
registering them with mdiobus_register_board_info(). SPI and I2C buses
have a similar feature, we were missing this for MDIO devices, but this
is particularly useful for e.g: MDIO-connected switches which need to
provide their port layout (often board-specific) to a MDIO Ethernet
switch driver.

net: phy: Fix typo for MDIO module boilerplate comment

2017-01-24T18:37:50+00:00

The module boilerplate macro is named mdio_module_driver and not
module_mdio_driver, fix that.

net: mdio: add mdio45_ethtool_ksettings_get

2017-01-02T21:59:10+00:00

There is a function in mdio for the old ethtool api gset.
We add a new function mdio45_ethtool_ksettings_get for the
new ethtool api glinksettings.

net: mdio: Fix lockdep falls positive splat

2016-04-12T01:15:48+00:00

MDIO devices can be stacked upon each other. The current code supports
two levels, which until recently has been enough for a DSA mdio bus on
top of another bus. Now we have hardware which has an MDIO mux in the
middle.

Define an MDIO MUTEX class with three levels.

mdio: Abstract device_remove() and device_free()

2016-01-07T19:31:27+00:00

Make device_free and device_remove operations in the mdio device
structure, so the core code does not need to differentiate between
phy devices and generic mdio devices.

mdio: Add support for mdio drivers.

2016-01-07T19:31:27+00:00

Not all devices on an MDIO bus are PHYs. Meaning not all MDIO drivers
are PHY drivers. Add support for generic MDIO drivers.

phy: Move phy specific bus match into phy_device

2016-01-07T19:31:27+00:00

Matching a driver to a device has both generic parts, and parts which
are specific to PHY devices. Move the PHY specific parts into
phy_device.

phy: Move PHY PM operations into phy_device

2016-01-07T19:31:27+00:00

The MDIO PM operations are really PHY device PM operations. So move
them into phy_device. This will be needed when we support devices on
the mdio bus which are not PHYs.

phy: Add API for {un}registering an mdio device to a bus.

2016-01-07T19:31:26+00:00

Rather than have drivers directly manipulate the mii_bus structure,
provide and API for registering and unregistering devices on an MDIO
bus, and performing lookups.

phy: Add an mdio_device structure

2016-01-07T19:31:26+00:00

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.
