      of: mdio: Add a "broken-turn-around" property · ab6016e0
      Florian Fainelli 提交于
      Some Ethernet PHY devices/switches may not properly release the MDIO bus
      during turn-around time, and fail to drive it low, which can be seen by
      some controllers as a read failure, while the data clocked in is still
      correct.
      
      Add a boolean property "broken-turn-around" which is parsed by the
      generic MDIO bus probing code and will set the corresponding bit in the
      MDIO bus phy_ignore_ta_mask bitmask for MDIO bus drivers to utilize that
      information.

      net: phy: adjust fixed_phy_register() return value · fd2ef0ba
      Petri Gynther 提交于
      Adjust fixed_phy_register() to return struct phy_device *, so that
      it becomes easy to use fixed PHYs without device tree support:
      
        phydev = fixed_phy_register(PHY_POLL, &fixed_phy_status, NULL);
        fixed_phy_set_link_update(phydev, fixed_phy_link_update);
        phy_connect_direct(netdev, phydev, handler_fn, phy_interface);
      
      This change is a prerequisite for modifying bcmgenet driver to work
      without a device tree on Broadcom's MIPS-based 7xxx platforms.

      of: mdio: honor flags passed to of_phy_connect · 2f637151
      Florian Fainelli 提交于
      Commit f9a8f83b ("net: phy: remove flags argument from phy_{attach,
      connect, connect_direct}") removed the flags argument to the PHY library
      calls to: phy_{attach,connect,connect_direct}.
      
      Most Device Tree aware drivers call of_phy_connect() with the flag
      argument set to 0, but some of them might want to set a different value
      there in order for the PHY driver to key a specific behavior based on
      the phy_device::phy_flags value.
      
      Allow such drivers to set custom phy_flags as part of the
      of_phy_connect() call since of_phy_connect() does start the PHY state
      machine, it will call into the PHY driver config_init() callback which
      is usually where a specific phy_flags value is important.

      of: provide a binding for fixed link PHYs · 3be2a49e
      Thomas Petazzoni 提交于
      Some Ethernet MACs have a "fixed link", and are not connected to a
      normal MDIO-managed PHY device. For those situations, a Device Tree
      binding allows to describe a "fixed link" using a special PHY node.
      
      This patch adds:
      
       * A documentation for the fixed PHY Device Tree binding.
      
       * An of_phy_is_fixed_link() function that an Ethernet driver can call
         on its PHY phandle to find out whether it's a fixed link PHY or
         not. It should typically be used to know if
         of_phy_register_fixed_link() should be called.
      
       * An of_phy_register_fixed_link() function that instantiates the
         fixed PHY into the PHY subsystem, so that when the driver calls
         of_phy_connect(), the PHY device associated to the OF node will be
         found.
      
      These two additional functions also support the old fixed-link Device
      Tree binding used on PowerPC platforms, so that ultimately, the
      network device drivers for those platforms could be converted to use
      of_phy_is_fixed_link() and of_phy_register_fixed_link() instead of
      of_phy_connect_fixed_link(), while keeping compatibility with their
      respective Device Tree bindings.

      of_mdio: fix phy interrupt passing · f15c586d
      Ben Dooks 提交于
      The of_mdiobus_register_phy() is not setting phy->irq thus causing
      some drivers to incorrectly assume that the PHY does not have an
      IRQ associated with it. Not only do some drivers report no IRQ
      they do not install an interrupt handler for the PHY.
      
      Simplify the code setting irq and set the phy->irq at the same
      time so that we cover the following issues, which should cover
      all the cases the code will find:
      
      - Set phy->irq if node has irq property and mdio->irq is NULL
      - Set phy->irq if node has no irq and mdio->irq is not NULL
      - Leave phy->irq as PHY_POLL default if none of the above
      
      This fixes the issue:
       net eth0: attached PHY 1 (IRQ -1) to driver Micrel KSZ8041RNLI
      
      to the correct:
       net eth0: attached PHY 1 (IRQ 416) to driver Micrel KSZ8041RNLI

      netdev/phy/of: Handle IEEE802.3 clause 45 Ethernet PHYs in of_mdiobus_register() · 6bd47ac2
      David Daney 提交于
      Define two new "compatible" values for Ethernet
      PHYs. "ethernet-phy-ieee802.3-c22" and "ethernet-phy-ieee802.3-c45"
      are used to indicate a PHY uses the corresponding protocol.
      
      If a PHY is "compatible" with "ethernet-phy-ieee802.3-c45", we
      indicate this so that get_phy_device() can properly probe the device.
      
      If get_phy_device() fails, it was probably due to failing the probe of
      the PHY identifier registers.  Since we have the device tree telling
      us the PHY exists, go ahead and add it anyhow with a phy_id of zero.
      There may be a driver match based on the "compatible" property.

      netdev/phy: Handle IEEE802.3 clause 45 Ethernet PHYs · ac28b9f8
      David Daney 提交于
      The IEEE802.3 clause 45 MDIO bus protocol allows for directly
      addressing PHY registers using a 21 bit address, and is used by many
      10G Ethernet PHYS.  Already existing is the ability of MDIO bus
      drivers to use clause 45, with the MII_ADDR_C45 flag.  Here we add
      struct phy_c45_device_ids to hold the device identifier registers
      present in clause 45. struct phy_device gets a couple of new fields:
      c45_ids to hold the identifiers and is_c45 to signal that it is clause
      45.
      
      get_phy_device() gets a new parameter is_c45 to indicate that the PHY
      device should use the clause 45 protocol, and its callers are adjusted
      to pass false.  The follow-on patch to of_mdio.c will pass true where
      appropriate.
      
      EXPORT phy_device_create() so that the follow-on patch to of_mdio.c
      can use it to create phy devices for PHYs, that have non-standard
      device identifier registers, based on the device tree bindings.

      netdev/of/phy: New function: of_mdio_find_bus(). · 25106022
      David Daney 提交于
      Add of_mdio_find_bus() which allows an mii_bus to be located given its
      associated the device tree node.
      
      This is needed by the follow-on patch to add a driver for MDIO bus
      multiplexers.
      
      The of_mdiobus_register() function is modified so that the device tree
      node is recorded in the mii_bus.  Then we can find it again by
      iterating over all mdio_bus_class devices.
      
      Because the OF device tree has now become an integral part of the
      kernel, this can live in mdio_bus.c (which contains the needed
      mdio_bus_class structure) instead of of_mdio.c.

      driver-core: Add device node pointer to struct device · d706c1b0
      Grant Likely 提交于
      Currently, platforms using CONFIG_OF add a 'struct device_node *of_node'
      to dev->archdata.  However, with CONFIG_OF becoming generic for all
      architectures, it makes sense for commonality to move it out of archdata
      and into struct device proper.
      
      This patch adds a struct device_node *of_node member to struct device
      and updates all locations which currently write the device_node pointer
      into archdata to also update dev->of_node.  Subsequent patches will
      modify callers to use the archdata location and ultimately remove
      the archdata member entirely.
