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.
