Changes since v2:
- Rebased on tag v6.1.
- Dropped patch 8 because it was merged.
Patch 1:
- Made the links into "Link:" tags. (by Conor)
- Corrected the board name to "VisionFive 2" instead of
  "VisionFive V2" and added compatibles for version A and
  version B of VisionFive 2. (by Emil)
Patch 4:
- Used "sifive,ccache0" compatible string to match. (by Conor)
Patch 5:
- Dropped "select SIFIVE_CCACHE" in config SOC_STARFIVE. (by Conor)
- Dropped "starfive,jh7110-ccache" compatible in
  drivers/soc/sifive/sifive_ccache.c.
Patch 6:
- Removed all "clock-frequency = <0>". (by Conor)
- Sorted the nodes after their addresses. (by Emil)
- Renamed "clk_rtc" to "rtc_osc".
- Added "sifive,ccache0" compatible in the cache-controller node.
- Renamed "JH7110_SYSCLK_APB_BUS_FUNC" to "JH7110_SYSCLK_APB_BUS" and
  renamed "apb_bus_func" to "apb_bus".
  Renamed "JH7110_SYSCLK_IOMUX" to "JH7110_SYSCLK_IOMUX_APB".
  Renamed "JH7110_SYSRST_IOMUX" to "JH7110_SYSRST_IOMUX_APB".
  Renamed "JH7110_AONRST_AON_IOMUX" to "JH7110_AONRST_IOMUX".
- Removed "reg-names" in gpio nodes.
Patch 7:
- Corrected the board name to "VisionFive 2" instead of "VisionFive V2".
- Renamed jh7110-starfive-visionfive-v2.dts to
  jh7110-starfive-visionfive-2.dtsi.
- Added dts for VisionFive 2 version A and version B boards.
- In the chosen node, deleted "linux,initrd-start" and "linux,initrd-end"
  and changed the value of "stdout-path" to "serial0:115200n8".
- Changed the bias of uart0 "rx-pins" to
  "bias-disable; /* external pull-up */".
- Renamed "clk_rtc" to "rtc_osc".
- Moved the gpio node behind the uart0 node.

Changes since v1:
- Rebased on tag v6.1-rc5.
- Added blank line in patch 1. (by Krzysztof)
- Rebased patch 4 and 6 on the newest code. (by Conor)
- Dropped patch 5. (by Conor)
- Removed the quirk of JH7100 in patch 6, considering this patch series
  should only add support for JH7110.
- For patch 27, added Co-developed-by tag for Jianlong and me. Renamed
  cpu labels to "S76_0", "U74_*" instead of "cpu*" following the style
  of jh7100.dtsi. Moved all "clock-frequency" properties to the board dts.
  Rewrote clock-controller nodes and deleted reset-controller nodes for
  using auxiliary bus. Rewrote gpio nodes following generic pinctrl
  bindings. Removed the redundant second reset entry of uart nodes.
- For patch 28, added Co-developed-by tag for Jianlong and me. Added a
  chosen node. Removed reserved-memory node. Added fixed frequency clock
  nodes for overriding the "clock-frequency" properties. Rewrote the gpio
  nodes following generic pinctrl bindings.
- Dropped patch 30. (by Conor)
- Reworded the commit messages.
