KSZ9477 has the 11 bit ageing count value which is split across the two
registers. And LAN937x has the 20 bit ageing count which is also split
into two registers. Each count in the registers represents 1 second.
This patch add the support for ageing time for KSZ9477 and LAN937x
series of switch.

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.

PHY access may end with errors on different levels. So, allow to forward
return values where possible.

This patch add support for phylink mac config for ksz series of
switches. All the files ksz8795, ksz9477 and lan937x uses the ksz common
xmii function. Instead of calling from the individual files, it is moved
to the ksz common phylink mac config function.

This patch read the rgmii tx and rx delay from device tree and stored it
in the ksz_port. It applies the rgmii delay to the xmii tune adjust
register based on the interface selected in phylink mac config. There
are two rgmii port in LAN937x and value to be loaded in the register
vary depends on the port selected.

This patch add the support for common phylink mac link up for the ksz
series switch. The register address, bit position and values are
configured based on the chip id to the dev->info structure.

The internal phy of the LAN937x are capable of 100Mbps Full duplex. The
xMII port of switch is capable of 10Mbps Full & Half Duplex, 100Mbps
Full & Half Duplex and 1000Mbps Half duplex. xMII port also supports Tx
and Rx Flow control.

Basic DSA driver support for lan937x and the device will be
configured through SPI interface.
It adds the lan937x_dev_ops in ksz_common.c file and tries to reuse the
functionality of ksz9477 series switch.
drivers/net/dsa/microchip/ path is already part of MAINTAINERS &
the new files come under this path. Hence no update needed to the
MAINTAINERS
