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].

Patch 5: - Cleaned up all the error handling code by dev_err_probe (by Emil). - Fixed the warning that clang uses W=1 because 'rate' may not be initialized (by Jakub Kicinski) Changes history: Changes since v8: Patch 4: - Dropped irrelevant MAINTAINERS context (by Jakub Kicinski) Patch 6: - Moved error messages to starfive_dwmac_set_mode function to avoid getting error messages twice when syscon_regmap_lookup_by_phandle_args fails. (by Emil) - Renamed patch header to "net: stmmac: dwmac-starfive:xxx" (by Emil) Changes since v7: Patch 4: - Constrained the reg/interrupts/interrupt-names properties (by Krzysztof Kozlowski) Changes since v6: - Sended network patches[patch 1,2,3,4,5,6] and riscv trees patches[patch 7,8] separately (by Jakub Kicinski) Changes since v5: - Dropped "depends on STMMAC_ETH" and compiled DWMAC_STARFIVE to m by default (by Emil) - Removed clk_gtx in struct starfive_dwmac due to this pointer is only set, but never read. (by Emil) - Only setting the plat_dat->fix_mac_speed callback when it is needed (by Emil) - Moved mdio/phy nodes from SOC .dtsi into board .dtsi (by Andrew) - Modified the parameters passed by starfive,syscon (by Andrew && Emil) <syscon, offset, mask> ==> <syscon, offset, shift> - Optimized the patchs(Fewer patches from 12 to 8) 1)merged patch-7 into patch-4 (by Rob) 2)merged patch-9 into patch-5 2)merged patch-11,12 into patch-10 3)Adjusted the patchs order - Fixed the unevaluatedProperties property from true to false (by Rob) - Replaced contains:enum with items:const for reset-names in snps,dwmac.yaml (by Rob) - Tested-by: Tommaso Merciai <tomm.merciai@xxxxxxxxx> Changes since v4: - Supported both visionfive 2 v1.2A and visionfive 2 v1.3B. - Reworded the maxitems number of resets property in 'snps,dwmac.yaml'. - Suggested by Emil, dropped the _PLAT/_plat from the config/function/struct/file names. - Suggested by Emil, added MODULE_DEVICE_TABLE(). - Suggested by Emil, dropped clk_gtxclk and use clk_tx_inv to set the clock frequency. - Added phy interface mode configuration function. - Rebased on tag v6.2. Changes since v3: - Reworded the maxitems number of resets property in 'snps,dwmac.yaml' - Removed the unused code in 'dwmac-starfive-plat.c'. - Reworded the return statement in 'starfive_eth_plat_fix_mac_speed' function. Changes since v2: - Renamed the dt-bindings 'starfive,jh71x0-dwmac.yaml' to 'starfive,jh7110-dwmac.yaml'. - Reworded the commit messages. - Reworded the example context in the dt-binding 'starfive,jh7110-dwmac.yaml'. - Removed "starfive,jh7100-dwmac" compatible string and special initialization of jh7100. - Removed the parts of YT8531,so dropped patch 5 and 6. - Reworded the maxitems number of resets property in 'snps,dwmac.yaml'. Changes since v1: - Recovered the author of the 1st and 3rd patches back to Emil Renner Berthing. - Added a new patch to update maxitems number of resets property in 'snps,dwmac.yaml'. - Fixed the check errors reported by "make dt_binding_check". - Renamed the dt-binding 'starfive,dwmac-plat.yaml' to 'starfive,jh71x0-dwmac.yaml'. - Updated the example context in the dt-binding 'starfive,jh71x0-dwmac.yaml'. - Added new dt-binding 'motorcomm,yt8531.yaml' to describe details of phy clock delay configuration parameters. - Added more comments for PHY driver setting. For more details, see 'motorcomm,yt8531.yaml'. - Moved mdio device tree node from 'jh7110-starfive-visionfive-v2.dts' to 'jh7110.dtsi'. - Re-worded the commit message of several patches. - Renamed all the functions with starfive_eth_plat prefix in 'dwmac-starfive-plat.c'. - Added "starfive,jh7100-dwmac" compatible string and special init to support JH7100.
