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 through MII/RMII interface. The RGMII interface support will be added in the follow up series. LAN937x uses the most of functionality of KSZ9477. 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 Changes in v15: - fixed compilation issue. - Updated the phylink_mac_link_up to check only for 10/100/1000 speed. Changes in v14: - Updated the patch series to latest ksz code refactoring. - RGMII register configuration is removed from the series. It will be added in the follow up patch series. Changes in v13: - Fixed the compilation issue in patch 5 and 6 Changes in v12: - Removed the reduntant spi indirect enable in lan937x_init - Used the ksz_port_stp_state_set function - Apply rgmii internal delay only if it is rgmii port - Set the bit for 100baseTx in phylink_get_caps - Moved the ethtool related API from patch 5 to 7 - Moved lan_alu_entry struct in lan937x_dev.h from patch 5 to 9 - Moved lan_vlan_entry in lan937x_dev.h from patch 5 to 10 - Used the ksz_get_stats64 function for get_stats64 hook - Splitted the patch 5. one for port configuration, spi driver, phy read & write and mtu configuration. - Updated the indentation in ethernet-controller.yaml - lan937x.yaml: Removed the blank lines, updated the ethernet handle to macb0.
