Merge tag 'irqchip-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core
Pull irqchip updates from Marc Zyngier:
- New and improved irqdomain locking, closing a number of races that
became apparent now that we are able to probe drivers in parallel
- A bunch of OF node refcounting bugs have been fixed
- We now have a new IPI mux, lifted from the Apple AIC code and
made common. It is expected that riscv will eventually benefit
from it
- Two small fixes for the Broadcom L2 drivers
- Various cleanups and minor bug fixes
