This work involves implementing a GMAC driver glue layer\nbased on Synopsys DWMAC driver framework to leverage MA35D1's dual GMAC\ninterface capabilities.\n\nOverview:\n 1. Added a GMAC driver glue layer for MA35D1 SoC, providing support for\n the platform's two GMAC interfaces.\n 2. Added device tree settings, with specific configurations for our\n development boards:\n a. SOM board: Configured for two RGMII interfaces.\n b. IoT board: Configured with one RGMII and one RMII interface.\n 3. Added dt-bindings for the GMAC interfaces.\n\nv15:\n - Return error correctly in probe function.\n\nv14:\n - Fixed dt_binding_check compilation errors in the YAML file.\n\nv13:\n - Fixed YAML with dt_binding_check\n - Added callback for plat_dat->phy_interface\n - Updated PHY-related setting helper function\n - Renamed registers and values to avoid misleading names\n\nv12:\n - Drop private structure nvt_priv_data\n - Fix error propagation to preserve probe deferral\n - Refactor internal delay handling into a dedicated helper\n - Move FIFO and filter configuration from driver to Device Tree\n - Update DT binding to include \"snps,dwmac-3.70a\" compatible\n\nv11:\n - Propagate syscon lookup errors to allow proper probe deferral.\n\nv10:\n - Update DTS/DTSI files to follow proper hierarchy and port modeling\n\nv9:\n - Fixed file permissions. (YAML, driver, DTS)\n - Moved phy-handle and PHY-related properties from SoC dtsi to board dts.\n\nv8:\n Changes since v7:\n - Rebased onto the latest net-next.\n - Removed unused symbol.\n - stmmac parent driver now reads hardware features directly to support\n Wake-on-LAN via magic packet, so PMT-related overrides in this driver\n have been removed.\n - Update dwmac-nuvoton driver:\n - Update the license to GPL.\n - Improve the description in Kconfig.\n\nv7:\n - Update dwmac-nuvoton driver\n - Update probe function to use stmmac_pltfr_probe instead.\n\nv6:\n - Update dwmac-nuvoton driver\n - Use NVT as the previx for all functions, structs, and defines.\n - Remove unnecessary comments.\n\nv5:\n - Update yaml\n - Remove the properties already defined in snps dwmac.\n - Update dwmac-nuvoton driver\n - Add a comment to explain the override of PMT flag.\n\nv4:\n - Update yaml\n - Remove unnecessary property 'select'.\n - Remove unnecessary compatible entries and fix items.\n - Specify number of entries for 'reg'.\n - Remove already defined property 'phy-handle'.\n - Update example.\n - Modify the property internal path delay to match the driver.\n - Update dtsi\n - Move 'status' to be the last property.\n - Update dwmac-nuvoton driver\n - Use remove instead of remove_new.\n - Use dev_err_probe instead.\n\nv3:\n - Update yaml\n - Fix for dt_binding_check warnings & errors.\n - Add compatible in snps dwmac.\n - Update dtsi\n - Update dtsi to follow examples in yaml.\n - Update dwmac-nuvoton driver\n - Fix for auto build test warnings.\n - Invalid path delay arguments will be returned.\n\nv2:\n - Update yaml\n - Rename file to align with the compatible property.\n - Add an argument to syscon to replace mac-id,\n with corresponding descriptions.\n - Use tx-internal-delay-ps and rx-internal-delay-ps properties for\n configurable path delay with corresponding descriptions,\n allowing selection between GMAC internal and PHY.\n - Add all supported phy-mode options.\n - Remove unused properties.\n - Update dtsi\n - Modify syscon configuration to include an argument for\n GMAC interface selection.\n - Update dwmac-nuvoton driver\n - Remove redundant device information print statements.\n - Remove non-global parameters.\n - Retrieve GMAC interface selection from the syscon argument.\n - Parse Tx and Rx path delays by correct properties.\n - Update configurations to support Wake-on-LAN.\n\nJoey Lu (3):\n dt-bindings: net: nuvoton: Add schema for Nuvoton MA35 family GMAC\n arm64: dts: nuvoton: Add Ethernet nodes\n net: stmmac: dwmac-nuvoton: Add dwmac glue for Nuvoton MA35 family\n\n .../bindings/net/nuvoton,ma35d1-dwmac.yaml | 140 ++++++++++++++++++\n .../devicetree/bindings/net/snps,dwmac.yaml | 1 +\n .../boot/dts/nuvoton/ma35d1-iot-512m.dts | 25 ++++\n .../boot/dts/nuvoton/ma35d1-som-256m.dts | 24 +++\n arch/arm64/boot/dts/nuvoton/ma35d1.dtsi | 52 +++++++\n drivers/net/ethernet/stmicro/stmmac/Kconfig | 12 ++\n drivers/net/ethernet/stmicro/stmmac/Makefile | 1 +\n .../ethernet/stmicro/stmmac/dwmac-nuvoton.c | 136 +++++++++++++++++\n 8 files changed, 391 insertions(+)\n create mode 100644 Documentation/devicetree/bindings/net/nuvoton,ma35d1-dwmac.yaml\n create mode 100644 drivers/net/ethernet/stmicro/stmmac/dwmac-nuvoton.c"}
