[PATCH 0/2] riscv-imsic/aplic: Save and restore the registers

[Nick Hu]

Since the APLIC and IMSIC may be powered down when the CPUs enter a deep
sleep state, it is necessary to implement save and restore functions to
ensure their states are correctly preserved and restored.

Nick Hu (2):
  irqchip/riscv-imsic: Restore the IMSIC register
  irqchip/riscv-aplic: Add save and restore functions
