[Hal Feng <hal.feng@starfivetech.com>]

VisionFive 2 Lite is a mini SBC based on the StarFive JH7110S industrial
SoC which can run at -40~85 degrees centigrade and up to 1.25GHz.

Board features:
- JH7110S SoC
- 4/8 GiB LPDDR4 DRAM
- AXP15060 PMIC
- 40 pin GPIO header
- 1x USB 3.0 host port
- 3x USB 2.0 host port
- 1x M.2 M-Key (size: 2242)
- 1x MicroSD slot (optional non-removable 64GiB eMMC)
- 1x QSPI Flash
- 1x I2C EEPROM
- 1x 1Gbps Ethernet port
- SDIO-based Wi-Fi & UART-based Bluetooth
- 1x HDMI port
- 1x 2-lane DSI

Changes since v2:
- Drop patch 3, 4, 5.
patch 6:
- jh7110s-starfive-visionfive-2-lite.dtsi directly includes "jh7110.dtsi"
  instead of "jh7110s-common.dtsi".

Changes since v1:
- Drop patch 1 because it is applied.
- Rename jh7110.dtsi to jh711x.dtsi.
- Move the content of jh7110-common.dtsi to the new file
  jh711x-common.dtsi and move opp table to jh7110-common.dtsi.
patch 4:
- Move the uncommon nodes to jh7110-common.dtsi instead of board dts.
patch 5:
- Add jh7110s-common.dtsi and include it in jh7110s-starfive-visionfive-2-lite.dtsi.

Changes since RFC:
- Add jh7110s compatible to the generic cpufreq driver.
- Fix the dtbs_check error by adding the missing "enable-gpios" property
  in jh7110 pcie dt-bindings.
- Rebase on the latest mainline.
- Add VisionFive 2 Lite eMMC board device tree and add a common board dtsi
  for VisionFive 2 Lite variants.
- Add usb switch pin configuration (GPIO62).
- Improve the commit messages.
