Subject: [PATCH v6 0/8] Add Ethernet driver for StarFive JH7110 SoC

This series adds ethernet support for the StarFive JH7110 RISC-V SoC.
The series includes MAC driver. The MAC version is dwmac-5.20 (from
Synopsys DesignWare). 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].

Changes since v5:
- Droped "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@...il.com>
- Rebased on tag v6.3-rc1

Changes history:

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.
