[PATCH v5 00/12] Add Ethernet driver for StarFive JH7110 SoC

[Samin Guo]

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], [5].

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.

Patch 12:
- No update
Patch 11:
- Configuration of gmac and phy for visionfive 2 v1.2A.
Patch 10:
- Configuration of gmac and phy for visionfive 2 v1.3B.
Patch 9:
- Added starfive,syscon for gmac nodes in jh7110.dtsi.
Patch 8:
- Added starfive_dwmac_set_mode to set PHY interface mode.
Patch 7:
- Added starfive,syscon item in StarFive-dwmac dt-bindings.
Patch 6:
- Moved SOC_STARFIVE to ARCH_STARFIVE in Kconfig.
- Dropped the _PLAT/_plat from the config/function/struct names. (by Emil)
- Added MODULE_DEVICE_TABLE() and udev will load the module automatically. (by Emil)
- Used { /* sentinel */ } for the last entry of starfive_eth_match. (by Emil)
- Added 'tx_use_rgmii_rxin_clk' to struct starfive_dwmac, to mark the clk_tx'parent is rgmii.
- Suggested by Emil, dropped clk_gtxclk and use clk_tx_inv to set the clock frequency.
Patch 5:
- Suggested by Emil, dropped mdio0/1 labels because there is no reference elsewhere.
Patch 4:
- Removed GTXC clk in StarFive-dwmac dt-bindings.
- Added starfive,tx-use-rgmii-clk item in StarFive-dwmac dt-bindings.
Patch 3:
- Added an optional reset single 'ahb' in 'snps,dwmac.yaml', according to
  stmmac_probe_config_dt/stmmac_dvr_probe.
Patch 2:
- No update
Patch 1:
- No update

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.
