da53af8cb9 net: dsa: microchip: fix Clang -Wunused-const-variable warning on 'ksz_dt_ids' 
This patch removes the of_match_ptr() pointer when dereferencing the
ksz_dt_ids which produce the unused variable warning.

47d82864ee net: dsa: microchip: remove the struct ksz8 
This patch removes the struct ksz8 from ksz8.h which is no longer
needed. The platform bus specific details are now deferenced through
dev->priv.

4658f2fe8f net: dsa: microchip: common ksz_spi_probe for ksz switches 
As of now, there are two spi probes, one ksz8795_spi.c and other
ksz9477_spi.c. This patch combines two files into single ksz_spi.c. The
difference between the two are regmap config and struct ksz8. The regmap
config is assigned based on the platform data. And struct ksz8 is left
untouched, as it is used only ksz8795.c. It can be used for all
other switches also in future.

b987e98e50 dsa: add DSA switch driver for Microchip KSZ9477 
The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch
with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs.
The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII
or RMII. Either of these may connect directly to a host processor or
to an external PHY. The SGMII port may interface to a fiber optic transceiver.

This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.
