net: ti: icssm-prueth: Adds ICSSM Ethernet driver

2025-09-14T20:00:54Z

Updates Kernel configuration to enable PRUETH driver and its dependencies along with makefile changes to add the new PRUETH driver. Changes includes init and deinit of ICSSM PRU Ethernet driver including net dev registration and firmware loading for DUAL-MAC mode running on PRU-ICSS2 instance. Changes also includes link handling, PRU booting, default firmware loading and PRU stopping using existing remoteproc driver APIs.

net: ti: icssg-prueth: Split out common object into module

2024-07-15T12:50:40Z

icssg_prueth.c and icssg_prueth_sr1.c drivers use multiple common .c files. These common objects are getting added to multiple modules. As a result when both drivers are enabled in .config, below warning is seen. drivers/net/ethernet/ti/Makefile: icssg/icssg_common.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_classifier.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_config.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_mii_cfg.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_stats.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_ethtool.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 Fix this by building a new module (icssg.o) for all the common objects. Both the driver can then depend on this common module. Some APIs being exported have emac_ as the prefix which may result into confusion with other existing APIs with emac_ prefix, to avoid confusion, rename the APIs being exported with emac_ to icssg_ prefix. This also fixes below error seen when both drivers are built. ERROR: modpost: "icssg_queue_pop" [drivers/net/ethernet/ti/icssg-prueth-sr1.ko] undefined!

net: ti: icssg-prueth: Add support for ICSSG switch firmware

2024-05-30T13:37:26Z

Add support for ICSSG switch firmware using existing Dual EMAC driver with switchdev. Limitations: VLAN offloading is limited to 0-256 IDs. MDB/FDB static entries are limited to 511 entries and different FDBs can hash to same bucket and thus may not completely offloaded Example assuming ETH1 and ETH2 as ICSSG2 interfaces: Switch to ICSSG Switch mode: ip link add name br0 type bridge ip link set dev eth1 master br0 ip link set dev eth2 master br0 ip link set dev br0 up bridge vlan add dev br0 vid 1 pvid untagged self Going back to Dual EMAC mode: ip link set dev br0 down ip link set dev eth1 nomaster ip link set dev eth2 nomaster ip link del name br0 type bridge By default, Dual EMAC firmware is loaded, and can be changed to switch mode by above steps Reviewed-by: Andrew Lunn Signed-off-by: MD Danish Anwar Signed-off-by: Paolo Abeni

net: ti: icssg-prueth: Add ICSSG Ethernet driver for AM65x SR1.0 platforms

2024-04-09T07:47:29Z

Add the PRUeth driver for the ICSSG subsystem found in AM65x SR1.0 devices. The main differences that set SR1.0 and SR2.0 apart are the missing TXPRU core in SR1.0, two extra DMA channels for management purposes and different firmware that needs to be configured accordingly. Based on the work of Roger Quadros, Vignesh Raghavendra and Grygorii Strashko in TI's 5.10 SDK [1].

net: ethernet: am65-cpsw: Rename TI_AM65_CPSW_TAS to TI_AM65_CPSW_QOS

We will use this Kconfig option to not only enable TAS/EST offload but also other QoS features like Multiqueue priority descriptors and MAC-Merge/Frame Preemption. TI_AM65_CPSW_QOS seems a more appropriate Kconfig option name than TI_AM65_CPSW_TAS. Signed-off-by: Roger Quadros Reviewed-by: Vladimir Oltean Signed-off-by: David S. Miller

net: cpmac: remove driver to prepare for platform removal

2023-10-05T23:48:55Z

AR7 is going to be removed from the Kernel, so remove its networking support in form of the cpmac driver. This allows us to remove the platform because this driver includes a platform specific header.
