This is based on next-20250922. Changes since v6: - Collected acks for DT binding patch - Rebased onto next-20250922 Changes since v5: - Use plat->phy_interface instead of plat->mac_interface (Russell) - Link to v5 https://lore.kernel.org/all/20250911174032.3147192-1-wens@kernel.org/ Changes since v4: - Moved clock-names list to main schema in DT binding (Rob) - Dropped 4 patches that are already merged - Link to v4 https://lore.kernel.org/all/20250908181059.1785605-1-wens@kernel.org/ Changes since v3: - driver - Fixed printf format specifier warning - Link to v3 https://lore.kernel.org/all/20250906041333.642483-1-wens@kernel.org/ Changes since v2: - DT binding - Added "select" to avoid matching against all dwmac entries - driver - Include "ps" unit in "... must be multiple of ..." error message - Use FIELD_FIT to check if delay value is in range and FIELD_MAX to get the maximum value - Reword error message for delay value exceeding maximum - Drop MASK_TO_VAL - Link to v2: https://lore.kernel.org/all/20250813145540.2577789-1-wens@kernel.org/ Changes since v1: - Dropped RFT tag - Switched to generic (tx|rx)-internal-delay-ps - dwmac-sun55i driver bits - Changed dev_err() + return to dev_err_probe() - Added check of return value from syscon regmap write - Changed driver name to match file name - sram driver bits - Fixed check on return value - Expanded commit message - dtsi - Fixed typo in tx-queues-config - cubie a5e - Add PHY regulator delay - Link to v1: https://lore.kernel.org/all/20250701165756.258356-1-wens@kernel.org/ This series adds support for the second Ethernet controller found on the Allwinner A523 SoC family. This controller, dubbed GMAC200, is a DWMAC4 core with an integration layer around it. The integration layer is similar to older Allwinner generations, but with an extra memory bus gate and separate power domain. Patch 1 adds a new compatible string combo to the existing Allwinner EMAC binding. Patch 2 adds a new driver for this core and integration combo. Patch 3 adds a device node and pinmux settings for the GMAC200. Patches 4, 5, and 6 enable the GMAC200 on three boards. I only tested the Orangepi 4A and Radxa Cubie A5E. Please have a look and help test on the Avaota A1. I don't expect any issues there though, since the PHY is always on, unlike on the Cubie A5E. Patches 1 and 2 should go through net-next, and I will take all the other patches through the sunxi tree. Hopefully we can get this merged for v6.18.
