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

2.36.1
This patch enables the interrupts for internal phy link detection for
LAN937x. The interrupt enable bits are active low. There is global
interrupt mask for each port. And each port has the individual interrupt
mask for TAS. QCI, SGMII, PTP, PHY and ACL.
The first level of interrupt domain is registered for global port
interrupt and second level of interrupt domain for the individual port
interrupts. The phy interrupt is enabled in the lan937x_mdio_register
function. Interrupt from which port is raised will be detected based on
the interrupt host data.

In the lan937x_reset_switch(), it masks all the switch and port
registers. In the Global_Int_status register, POR ready bit is write 1
to clear bit and all other bits are read only. So, this patch clear the
por_ready_int status bit by writing 1.
