From ffda5c62878fcd86ec9f1d0122027e7710f9566b Mon Sep 17 00:00:00 2001 From: Lothar Rubusch Date: Sat, 2 Nov 2024 11:41:21 +0000 Subject: [PATCH 1/2] net: stmmac: add support for dwmac 3.72a The dwmac 3.72a is an ip version that can be found on Intel/Altera Arria10 SoCs. Going by the hardware features "snps,multicast-filter-bins" and "snps,perfect-filter-entries" shall be supported. Thus add a compatibility flag, and extend coverage of the driver for the 3.72a.

Each EMAC can be used to transmit and receive data at 10/100/1000 Mbps over ethernet connections in compliance with the IEEE 802.3 specification. The EMACs on the Arria10 are instances of the Synopsis DesignWare Universal 10/100/1000 Ethernet MAC, version 3.72a. Support the Synopsis DesignWare version 3.72a, which is used in Intel's Arria10 SoC, since it was missing.
