* | phy_device: Move phy attributes into phy_deviceAndrew Lunn2016-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mdio_bus exports three attributes: - PHY ID is the unique 32-bits identifier for a MDIO device implementing standard MII registers MII_PHYSID1/2, which is not guaranteed to be the case for non-standard compliant devices (e.g: Ethernet switches) - PHY interface describes the data-path of the PHY/MDIO device, which is not strictly a PHY thing, but is required and needed for PHY devices to function, a MDIO device could be a control device exclusively - PHY has fixups describes what the PHY driver may have done, so completely PHY specific These are all phy attributes, not generic mdio attributes. So move the attributes into the phy device code. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This broken the Micrel PHY driver which has a deprecated feature of allowing PHY properties to be placed into the MAC node. In order to find the MAC node, we need to walk up the tree of devices until we find one with an OF node attached.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the Broadcom Cygnus SoCs internal PHY's. The PHYs are 1000M/100M/10M capable with support for 'EEE' and 'APD' (Auto Power Down). This driver supports the following Broadcom Cygnus SoCs: - BCM583XX (BCM58300, BCM58302, BCM58303, BCM58305) - BCM113XX (BCM11300, BCM11320, BCM11350, BCM11360) The PHY's on these SoC's require some workarounds for stable operation, both during configuration time and during suspend/resume. This driver handles the application of the workarounds. Signed-off-by: Arun Parameswaran <arunp@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The MDIO interface can be found in the Broadcom iProc family Soc's. The MDIO bus is accessed using a combination of command and data registers. This MDIO driver provides access to the Etherent GPHY's connected to the MDIO bus. Signed-off-by: Arun Parameswaran <arunp@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a helper to allow ethernet drivers to limit the speed of a phy (that they are attached to). This mainly involves factoring out the business-end of of_set_phy_supported() and exporting a new symbol. This code seems to be open coded in several places, in several different variants. It is is envisaged that this will be used in situations where setting the "max-speed" property in DT is not appropriate, e.g. because the maximum speed is not a property of the phy hardware.
