Subject: [PATCH net-next 0/8] net: dsa: microchip: DSA driver support for LAN937x switch

LAN937x is a Multi-Port 100BASE-T1 Ethernet Physical Layer switch 
compliant with the IEEE 802.3bw-2015 specification. The device 
provides 100 Mbit/s transmit and receive capability over a single
Unshielded Twisted Pair (UTP) cable. LAN937x is successive revision
of KSZ series switch. This series of patches provide the DSA driver 
support for Microchip LAN937X switch and it configures through 
SPI interface.

This driver shares some of the functions from KSZ common
layer.

The LAN937x switch series family consists of following SKUs:
LAN9370:
  - 4 T1 Phys
  - 1 RGMII port
LAN9371:
  - 3 T1 Phys & 1 TX Phy
  - 2 RGMII ports
LAN9372:
  - 5 T1 Phys & 1 TX Phy
  - 2 RGMII ports
LAN9373:
  - 5 T1 Phys
  - 2 RGMII & 1 SGMII port
LAN9374:
  - 6 T1 Phys
  - 2 RGMII ports

More support will be added at a later stage.
