[-net-next,v11,0/6] 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].

Changes since v10:
Patch 4:
- Required goes after properties (by Krzysztof Kozlowski)
Patch 5:
- Fixed the wrong binding filename (by Conor Dooley)

Changes history:

Changes since v9:
- Rebased on tag v6.3-rc4.
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 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@gmail.com>

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.
