Subject: [PATCH 0/7] Initial device tree support for StarFive JH8100 SoC

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.

Sia Jee Heng (7):
  dt-bindings: riscv: Add StarFive Dubhe compatibles
  dt-bindings: riscv: Add StarFive JH8100 SoC
  dt-bindings: timer: Add StarFive JH8100 clint
  dt-bindings: interrupt-controller: Add StarFive JH8100 plic
  dt-bindings: xilinx: Add StarFive compatible string
  serial: xilinx_uartps: Add new compatible string for StarFive
  riscv: dts: starfive: Add initial StarFive JH8100 device tree
