Merge branch 'add-ethernet-driver-for-starfive-jh7110-soc'
Samin Guo says: ==================== Add Ethernet driver for StarFive JH7110 SoC This series adds ethernet support for the StarFive JH7110 RISC-V SoC, which includes a dwmac-5.20 MAC driver (from Synopsys DesignWare). This series has been tested and works fine on VisionFive-2 v1.2A and v1.3B SBC boards. For more information and support, you can visit RVspace wiki[1]. You can simply review or test the patches at the link [2]. This patchset should be applied after the patchset [3] [4].
