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. ==================== Signed-off-by: David S. Miller --- 3aaf8630bf104906043211bafdf491a889972502
