[PATCH 0/5] Add Sipeed Lichee Pi 4A RISC-V board support

[Jisheng Zhang]

Sipeed's Lichee Pi 4A development board uses Lichee Module 4A core
module which is powered by T-HEAD's light(a.k.a TH1520) SoC. Add
minimal device tree files for the core module and the development
board.

Support basic uart/gpio/dmac drivers, so supports booting to a basic
shell.

Jisheng Zhang (5):
  irqchip/sifive-plic: Support T-HEAD's C910 PLIC
  riscv: Add the T-HEAD SoC family Kconfig option
  riscv: dts: add initial T-HEAD light SoC device tree
  riscv: dts: thead: add sipeed Lichee Pi 4A board device tree
  MAINTAINERS: add entry for T-HEAD RISC-V SoC
