      Merge branch 'mv88e6xxx-interrupt-support' · 3aaf8630
      由 David S. Miller 提交于 
      Andrew Lunn says:

====================
Interrupt support for mv88e6xxx

This patchset add interrupt controller support to the MV88E6xxx.  This
allows access to the interrupts the internal PHY generate. These
interrupts can then be associated to a PHY device in the device tree
and used by the PHY lib, rather than polling.

Since interrupt handling needs to make MDIO bus accesses, threaded
interrupts are used. The phylib needs to request the PHY interrupt
using the threaded IRQ API. This in term allows some simplification to
the code, in that the phylib interrupt handler can directly call
phy_change(), rather than use a work queue. The work queue is however
retained for the phy_mac_interrupt() call, which can be called in hard
interrupt context.

Since RFC v1:

Keep phy_mac_interrupt() callable in hard IRQ context.

The fix to trigger the phy state machine transitions on interrupts has
already been submitted, so is dropped from here.

Added back shared interrupts support.

      arm: vf610: zii devel b: Add support for switch interrupts · f283745b
      由 Andrew Lunn 提交于 
      The Switches use GPIO lines to indicate interrupts from two of the
switches.

With these interrupts in place, we can make use of the interrupt
controllers within the switch to indicate when the internal PHYs
generate an interrupt. Use standard PHY properties to do this.

      net: phy: Use phy name when requesting the interrupt · ae0219cb
      由 Andrew Lunn 提交于 
      Using the fixed name "phy_interrupt" is not very informative in
/proc/interrupts when there are a lot of phys, e.g. a device with an
Ethernet switch. So when requesting the interrupt, use the name of the
phy.

      net: phy: Threaded interrupts allow some simplification · 664fcf12
      由 Andrew Lunn 提交于 
      The PHY interrupts are now handled in a threaded interrupt handler,
which can sleep. The work queue is no longer needed, phy_change() can
be called directly. phy_mac_interrupt() still needs to be safe to call
in interrupt context, so keep the work queue, and use a helper to call
phy_change().
