Subject: [Patch net-next 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 v3 -> Patch v1
- Removed the RFC v3 1/3 from the series - changing exit from reset
- Changed the variable name in ksz_port from irq to pirq
- Added the check for return value of irq_find_mapping during phy irq
  registeration.
- Moved the clearing of POR_READY_INT from girq_thread_fn to
  lan937x_reset_switch

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: add reference to ksz_device inside the ksz_port
  net: dsa: microchip: lan937x: clear the POR_READY_INT status bit
  net: dsa: microchip: lan937x: add interrupt support for port phy link
