irqchip/apple-aic: Add support for the Apple Interrupt Controller
This is the root interrupt controller used on Apple ARM SoCs such as the M1. This irqchip driver performs multiple functions: * Handles both IRQs and FIQs * Drives the AIC peripheral itself (which handles IRQs) * Dispatches FIQs to downstream hard-wired clients (currently the ARM timer). * Implements a virtual IPI multiplexer to funnel multiple Linux IPIs into a single hardware IPI Reviewed-by: Marc Zyngier <maz@kernel.org> Acked-by: Will Deacon <will@kernel.org> Signed-off-by: Hector Martin <marcan@marcan.st>
