      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.

      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.

      net: dsa: mv88e6xxx: Poll when no interrupt defined · 294d711e
      Andrew Lunn 提交于
      Not all boards have the interrupt output from the switch connected to
      a GPIO line. In such cases, phylib has to poll the internal PHYs,
      rather than receive an interrupt when there is a change in the link
      state. phylib polls once per second, and per PHY reads around 4
      words. With a switch typically having 4 internal PHYs, this means 16
      MDIO transactions per second.
      
      Rather than performing this phylib level polling, have the driver poll
      the interrupt status register. If the status register indicates an
      interrupt condition processing of interrupts in the same way as if a
      GPIO was used.
      
      Polling 10 times a second places less load on the MDIO bus. But rather
      than taking on average 0.5s to detect a link change, it takes less
      than 0.05s. Additionally, other interrupts, such as the watchdog, ATU
      and VTU violations will be reported.
