net: ethernet: adi: Add ADIN1110 supportThe ADIN1110 is a low power single port 10BASE-T1L MAC-PHYdesigned for industrial Ethernet applications. It integratesan Ethernet PHY core with a MAC and all the associated analogcircuitry, input and output clock buffering.ADIN1110 MAC-PHY encapsulates the ADIN1100 PHY. The PHY registerscan be accessed through the MDIO MAC registers.We are registering an MDIO bus with custom read/write in orderto let the PHY to be discovered by the PAL. This will letthe ADIN1100 Linux driver to probe and take control ofthe PHY.The ADIN2111 is a low power, low complexity, two-Ethernet portsswitch with integrated 10BASE-T1L PHYs and one serial peripheralinterface (SPI) port.The device is designed for industrial Ethernet applications usinglow power constrained nodes and is compliant with the IEEE 802.3cg-2019Ethernet standard for long reach 10 Mbps single pair Ethernet (SPE).The switch supports various routing configurations betweenthe two Ethernet ports and the SPI host port providing a flexiblesolution for line, daisy-chain, or ring network topologies.The ADIN2111 supports cable reach of up to 1700 meters with ultralow power consumption of 77 mW. The two PHY cores support the1.0 V p-p operating mode and the 2.4 V p-p operating mode definedin the IEEE 802.3cg standard.The device integrates the switch, two Ethernet physical layer (PHY)cores with a media access control (MAC) interface and all theassociated analog circuitry, and input and output clock buffering.The device also includes internal buffer queues, the SPI andsubsystem registers, as well as the control logic to manage the resetand clock control and hardware pin configuration.Access to the PHYs is exposed via an internal MDIO bus. Writes/readscan be performed by reading/writing to the ADIN2111 MDIO registersvia SPI.On probe, for each port, a struct net_device is allocated andregistered. When both ports are added to the same bridge, the driverwill enable offloading of frame forwarding at the hardware level.Driver offers STP support. Normal operation on forwarding state.Allows only frames with the 802.1d DA to be passed to the hostwhen in any of the other states.When both ports of ADIN2111 belong to the same SW bridge a maximumof 12 FDB entries will offloaded by the hardware and are marked as such.Co-developed-by: Lennart Franzen Signed-off-by: Lennart Franzen Signed-off-by: Alexandru Tachici Signed-off-by: Paolo Abeni List of files: /linux-6.15/drivers/net/ethernet/adi/Makefile
