This work involves implementing a GMAC driver glue layer based on Synopsys DWMAC driver framework to leverage MA35D1's dual GMAC interface capabilities. Overview: 1. Added a GMAC driver glue layer for MA35D1 SoC, providing support for the platform's two GMAC interfaces. 2. Added device tree settings, with specific configurations for our development boards: a. SOM board: Configured for two RGMII interfaces. b. IoT board: Configured with one RGMII and one RMII interface. 3. Added dt-bindings for the GMAC interfaces. v11: - Propagate syscon lookup errors to allow proper probe deferral. v10: - Update DTS/DTSI files to follow proper hierarchy and port modeling v9: - Fixed file permissions. (YAML, driver, DTS) - Moved phy-handle and PHY-related properties from SoC dtsi to board dts. v8: Changes since v7: - Rebased onto the latest net-next. - Removed unused symbol. - stmmac parent driver now reads hardware features directly to support Wake-on-LAN via magic packet, so PMT-related overrides in this driver have been removed. - Update dwmac-nuvoton driver: - Update the license to GPL. - Improve the description in Kconfig. v7: - Update dwmac-nuvoton driver - Update probe function to use stmmac_pltfr_probe instead. v6: - Update dwmac-nuvoton driver - Use NVT as the previx for all functions, structs, and defines. - Remove unnecessary comments. v5: - Update yaml - Remove the properties already defined in snps dwmac. - Update dwmac-nuvoton driver - Add a comment to explain the override of PMT flag. v4: - Update yaml - Remove unnecessary property 'select'. - Remove unnecessary compatible entries and fix items. - Specify number of entries for 'reg'. - Remove already defined property 'phy-handle'. - Update example. - Modify the property internal path delay to match the driver. - Update dtsi - Move 'status' to be the last property. - Update dwmac-nuvoton driver - Use remove instead of remove_new. - Use dev_err_probe instead. v3: - Update yaml - Fix for dt_binding_check warnings & errors. - Add compatible in snps dwmac. - Update dtsi - Update dtsi to follow examples in yaml. - Update dwmac-nuvoton driver - Fix for auto build test warnings. - Invalid path delay arguments will be returned. v2: - Update yaml - Rename file to align with the compatible property. - Add an argument to syscon to replace mac-id, with corresponding descriptions. - Use tx-internal-delay-ps and rx-internal-delay-ps properties for configurable path delay with corresponding descriptions, allowing selection between GMAC internal and PHY. - Add all supported phy-mode options. - Remove unused properties. - Update dtsi - Modify syscon configuration to include an argument for GMAC interface selection. - Update dwmac-nuvoton driver - Remove redundant device information print statements. - Remove non-global parameters. - Retrieve GMAC interface selection from the syscon argument. - Parse Tx and Rx path delays by correct properties. - Update configurations to support Wake-on-LAN.
