This is due to next-20210128 including the device tree updates from
sunxi/sunxi/dt-for-5.12-late, but not the new driver from
irqchip/irq/irqchip-5.12. From [1]:

Merging irqchip/irq/irqchip-next (599b3063adf4 irqchip/mips-cpu: Set IPI
domain parent chip)

Where 599b3063adf4 is tag: irqchip-fixes-5.11-1.

Since then, irqchip/irq/irqchip-next has been updated to
irqchip/irq/irqchip-5.12, so this will be resolved in the next
linux-next release.

Cheers,
Samuel
