Subject: [RFC Patch net-next v3 0/3] net: dsa: microchip: lan937x: enable interrupt for internal phy link detection

This patch series enables the internal phy link detection for lan937x using the
interrupt method. lan937x acts as the interrupt controller for the internal
ports and phy, the irq_domain is registered for the individual ports and in
turn for the individual port interrupts.

RFC v2 -> v3
- Used the interrupt controller implementation of phy link

Changes in RFC v2
- fixed the compilation issue

Arun Ramadoss (3):
  net: dsa: microchip: use dev_ops->reset instead of exit in
    ksz_switch_register
  net: dsa: microchip: add reference to ksz_device inside the ksz_port
  net: dsa: microchip: lan937x: add interrupt support for port phy link
