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

[Arun Ramadoss <arun.ramadoss@microchip.com>]

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
