      Merge branch 'mv88e6xxx-auto-phy-intr' · ef57e31e

      ====================
      Automatic PHY interrupts
      
      Now that the mv88e6xxx driver either installs in interrupt handler, or
      polls for interrupts, it is possible to always handle PHY interrupts,
      rather than have phylib perform the polling. This speeds up detection
      of link changes and reduces the load on the MDIO bus, which is
      beneficial for PTP.

      net: dsa: mv88e6xxx: Add MDIO interrupts for internal PHYs · 6f88284f
      Andrew Lunn 提交于
      When registering an MDIO bus, it is possible to pass an array of
      interrupts, one per address on the bus. phylib will then associate the
      interrupt to the PHY device, if no other interrupt is provided.
      
      Some of the global2 interrupts are PHY interrupts. Place them into the
      MDIO bus structure.

      net: dsa: mv88e6xxx: Add number of internal PHYs · bc393155
      Andrew Lunn 提交于
      Add to the info structure the number of internal PHYs, if they generate
      interrupts. Some of the older generations of switches have internal
      PHYs, but no interrupt registers. In this case, set the count to zero.

      net: dsa: mv88e6xxx: Add missing g1 IRQ numbers · adfccf11
      Andrew Lunn 提交于
      With the recent change to polling for interrupts, it is important that
      the number of global 1 interrupts is listed. Without it, the driver
      requests an interrupt domain for zero interrupts, which returns
      EINVAL, and the probe fails.
      
      Add two missing entries.

      mv88e6xxx_get_ethtool_stats() calls mv88e6xxx_get_stats() which calls both

      chip->info->ops->serdes_get_stats() which does not. Have
      chip->info->ops->serdes_get_stats() be running with the register lock held to
      avoid such assertions.
