Merge branch irq/loongarch-of into irq/irqchip-next
* irq/loongarch-of:
: .
: Initial OF support for LoongArch. Funny how it only took
: *one* release from plumbing ACPI into an unsuspecting
: architecture to start enabling OF on it. Oh well...
: .
irqchip/loongarch-cpu: Fix a missing prototype warning
dt-bindings: interrupt-controller: add yaml for LoongArch CPU interrupt controller
irqchip: loongarch-cpu: add DT support
Signed-off-by: Marc Zyngier <maz@kernel.org>
