This GMAC device is based on a Synopsys IP and is compatible with the stmmac driver. My former colleague Clément Léger originally sent a series for this driver, but an issue in bringing up the PCS clock had blocked the upstreaming process. This issue has since been resolved by the following series: https://lore.kernel.org/all/20240326-rxc_bugfix-v6-0-24a74e5c761f@bootlin.com/ This series consists of a devicetree binding describing the RZN1 GMAC controller IP, a node for the GMAC1 device in the r9a06g032 SoC device tree, and the GMAC driver itself which is a glue layer in stmmac. There are also two patches by Russell that improve pcs initialization handling in stmmac. Best Regards, Romain Gantois --- Changes in v2: - Add pcs_init/exit callbacks in stmmac to solve race condition - Use pcs_init/exit callbacks in dwmac_socfpga glue layer - Miscellaneous device tree binding corrections - Link to v1: https://lore.kernel.org/r/20240402-rzn1-gmac1-v1-0-5be2b2894d8c@bootlin.com --- Clément Léger (3): dt-bindings: net: renesas,rzn1-gmac: Document RZ/N1 GMAC support net: stmmac: add support for RZ/N1 GMAC ARM: dts: r9a06g032: describe GMAC1 Russell King (Oracle) (2): net: stmmac: introduce pcs_init/pcs_exit stmmac operations net: stmmac: dwmac-socfpga: use pcs_init/pcs_exit .../devicetree/bindings/net/renesas,rzn1-gmac.yaml | 66 +++++++++++++ MAINTAINERS | 6 ++ arch/arm/boot/dts/renesas/r9a06g032.dtsi | 19 ++++ drivers/net/ethernet/stmicro/stmmac/Kconfig | 12 +++ drivers/net/ethernet/stmicro/stmmac/Makefile | 1 + drivers/net/ethernet/stmicro/stmmac/dwmac-rzn1.c | 88 +++++++++++++++++ .../net/ethernet/stmicro/stmmac/dwmac-socfpga.c | 109 +++++++++++---------- drivers/net/ethernet/stmicro/stmmac/stmmac_main.c | 14 +++ include/linux/stmmac.h | 2 + 9 files changed, 263 insertions(+), 54 deletions(-) --- base-commit: 87c33315af380ca12a2e59ac94edad4fe0481b4c change-id: 20240402-rzn1-gmac1-685cf8793d0e Best regards,
