[PATCH] PHY: Add support for configuring the PHY connection interface Most PHYs connect to an ethernet controller over a GMII or MII interface. However, a growing number are connected over different interfaces, such as RGMII or SGMII. The ethernet driver will tell the PHY what type of connection it is by setting it manually, or passing it in through phy_connect (or phy_attach).

[PATCH] phy address mask support for generic phy layer Adds a phy_mask field to struct mii_bus and uses it. This field indicates each phy address to be ignored when probing the mdio bus. This support is needed for the fs_enet and ibm_emac drivers to be converted to the generic phy layer among other drivers. Many systems lock up on probing certain phy addresses or probing doesn't return 0xffff when nothing is found at the address. A new driver I'm working on also makes use of this mask.

/* PHY state machine states:
*
* DOWN: PHY device and driver are not ready for anything. probe
* should be called if and only if the PHY is in this state,
* given that the PHY device exists.
* - PHY driver probe function will, depending on the PHY, set
* the state to STARTING or READY
*
* STARTING: PHY device is coming up, and the ethernet driver is
* not ready. PHY drivers may set this in the probe function.
* If they do, they are responsible for making sure the state is
* eventually set to indicate whether the PHY is UP or READY,
* depending on the state when the PHY is done starting up.
* - PHY driver will set the state to READY
* - start will set the state to PENDING
*
* READY: PHY is ready to send and receive packets, but the
* controller is not. By default, PHYs which do not implement
* probe will be set to this state by phy_probe(). If the PHY
* driver knows the PHY is ready, and the PHY state is STARTING,
* then it sets this STATE.
* - start will set the state to UP
*
* PENDING: PHY device is coming up, but the ethernet driver is
* ready. phy_start will set this state if the PHY state is
* STARTING.
* - PHY driver will set the state to UP when the PHY is ready
*
* UP: The PHY and attached device are ready to do work.
* Interrupts should be started here.
* - timer moves to AN
*
* AN: The PHY is currently negotiating the link state. Link is
* therefore down for now. phy_timer will set this state when it
* detects the state is UP. config_aneg will set this state
* whenever called with phydev->autoneg set to AUTONEG_ENABLE.
* - If autonegotiation finishes, but there's no link, it sets
* the state to NOLINK.
* - If aneg finishes with link, it sets the state to RUNNING,
* and calls adjust_link
* - If autonegotiation did not finish after an arbitrary amount
* of time, autonegotiation should be tried again if the PHY
* supports "magic" autonegotiation (back to AN)
* - If it didn't finish, and no magic_aneg, move to FORCING.
*
* NOLINK: PHY is up, but not currently plugged in.
* - If the timer notes that the link comes back, we move to RUNNING
* - config_aneg moves to AN
* - phy_stop moves to HALTED
*
* FORCING: PHY is being configured with forced settings
* - if link is up, move to RUNNING
* - If link is down, we drop to the next highest setting, and
* retry (FORCING) after a timeout
* - phy_stop moves to HALTED
*
* RUNNING: PHY is currently up, running, and possibly sending
* and/or receiving packets
* - timer will set CHANGELINK if we're polling (this ensures the
* link state is polled every other cycle of this state machine,
* which makes it every other second)
* - irq will set CHANGELINK
* - config_aneg will set AN
* - phy_stop moves to HALTED
*
* CHANGELINK: PHY experienced a change in link state
* - timer moves to RUNNING if link
* - timer moves to NOLINK if the link is down
* - phy_stop moves to HALTED
*
* HALTED: PHY is up, but no polling or interrupts are done. Or
* PHY is in an error state.
*
* - phy_start moves to RESUMING
*
* RESUMING: PHY was halted, but now wants to run again.
* - If we are forcing, or aneg is done, timer moves to RUNNING
* - If aneg is not done, timer moves to AN
* - phy_stop moves to HALTED
