Subject: [PATCH V2 0/4] irqchip/loongson: Add suspend/resume support for irqchip drivers

This series add suspend/resume support for Loongson-related irqchip
drivers (i.e., HTVECINTC, EIOINTC, PCH-PIC and PCH_LPC), which is needed
for LoongArch's upcoming suspend/hibernation support.

Note: this series is applicable after "irqchip/loongson-htvec: Add ACPI
init support".

V1 -> V2:
Holding irq_desc->lock while eiointc_set_irq_affinity().

Huacai Chen (4):
 irqchip/loongson-htvec: Add suspend/resume support.
 irqchip/loongson-eiointc: Add suspend/resume support.
 irqchip/loongson-pch-pic: Add suspend/resume support.
 irqchip/loongson-pch-lpc: Add suspend/resume support.
