StarFive JH8100 SoC consists of 4 RISC-V performance Cores (Dubhe-90) and
2 RISC-V energy efficient cores (Dubhe-80). It also features various
interfaces such as DDR4, Gbit-Ether, CAN, USB 3.2, SD/MMC, etc., making it
ideal for high-performance computing scenarios.

This patch series introduces initial SoC DTSI support for the StarFive
JH8100 SoC. The relevant dt-binding documentation has been updated
accordingly. Below is the list of IP blocks added in the initial SoC DTSI,
which can be used for booting via initramfs on FPGA:

- StarFive Dubhe-80 CPU
- StarFive Dubhe-90 CPU
- PLIC
- CLINT
- UART

The primary goal is to include foundational patches so that additional
drivers can be built on top of this framework.

Changes since v1:
- Dropped patch 5.
- Moved timebase-frequency from .dts to .dtsi.
- Moved soc node from .dts to .dtsi.
- Revised the title for the dt-binding document by removing Xilinx
  wording.
- Added a full stop to the end of the commit messages.
- Removed extra blank lines.
- Used hyphen for a node name.
- Added more recipients to the mailing list.
