"These patches have a dependency on an SOC patch, which we are including at the end of this series for reference. The SOC patch has been submitted in a separate thread [2] and we are awaiting for it to be merged." SOC patch need to be applied prior applying the "net" patches. We have changed the order and appended the SOC patch at the end, because SOC changes need to go into linux-next but not into net-next. We have make sure every individual patch has compiled successfully with W=1 if we apply SOC patch prior to the "net" patches. Thanks and Regards, Parvathi.

Please resubmit after the merge window.
Hi, The Programmable Real-Time Unit Industrial Communication Sub-system (PRU-ICSS) is available on the TI SOCs in two flavors: Gigabit ICSS (ICSSG) and the older Megabit ICSS (ICSSM). Support for ICSSG Dual-EMAC mode has already been mainlined [1] and the fundamental components/drivers such as PRUSS driver, Remoteproc driver, PRU-ICSS INTC, and PRU-ICSS IEP drivers are already available in the mainline Linux kernel. The current set of patch series builds on top of these components and introduces changes to support the Dual-EMAC mode on ICSSM, especially on the TI AM57xx devices. TI AM57xx series of devices have two identical PRU-ICSS instances (PRU-ICSS1 and PRU-ICSS2), each with two 32-bit RISC PRU cores. Each PRU core has (a) dedicated Ethernet interface (MII, MDIO), timers, capture modules, and serial communication interfaces, and (b) dedicated data and instruction RAM as well as shared RAM for inter PRU communication within the PRU-ICSS. These patches have a dependency on an SOC patch, which we are including at the end of this series for reference. The SOC patch has been submitted in a separate thread [2] and we are awaiting for it to be merged. These patches add support for the following features: - RX and TX over PRU Ethernet ports in Dual-EMAC mode - Full duplex with 100 Mbps link speed. - VLAN Filtering - Multicast Filtering - Promiscuous mode - Storm prevention - Interrupt coalescing - Linux PTP (ptp4l) Ordinary clock Further, note that these are the first set of patches for PRU-ICSS2 Ethernet. Switch mode support, PRU-ICSS1 support, PRU Ethernet for AM437x and AM335x in Dual-EMAC and Switch mode support with full feature set changes will be posted subsequently. The patches presented in this series have gone through the patch verification tools and no warnings or errors are reported. Sample test logs verifying the functionality on Linux next kernel are available here: [Interface up Testing](https://gist.github.com/ParvathiPudi/f481837cc6994e400284cb4b58972804) [Ping Testing](https://gist.github.com/ParvathiPudi/a121aad402defcef389e93f303d79317) [Iperf Testing](https://gist.github.com/ParvathiPudi/581db46b0e9814ddb5903bdfee73fc6f) [1] https://lore.kernel.org/all/20230106121046.886863-1-danishanwar@ti.com/ [2] https://lore.kernel.org/all/20250108125937.10604-1-basharath@couthit.com/ This is the v3 of the patch series [v1].
