Subject: [PATCH v4 0/7] Add Huashan Pi board support

Huashan Pi board is an embedded development platform based on the
CV1812H chip. Add minimal device tree files for this board.
Currently, it can boot to a basic shell.

NOTE: this series is based on the Jisheng's Milk-V Duo patch.

Changed from v3:
1. merge the patch 4 and 5 of v2 to preserve bisectability.

Changed from v2:
1. use dt override to save code.
2. code cleanup.

Changed from v1:
1. split the patch into several patch and refactor them.

Inochi Amaoto (7):
  dt-bindings: interrupt-controller: Add SOPHGO CV1812H plic
  dt-bindings: timer: Add SOPHGO CV1812H clint
  dt-bindings: riscv: Add SOPHGO Huashan Pi board compatibles
  riscv: dts: sophgo: Separate compatible specific for CV1800B soc
  riscv: dts: sophgo: cv18xx: Add gpio devices
  riscv: dts: sophgo: add initial CV1812H SoC device tree
  riscv: dts: sophgo: add Huashan Pi board device tree
