Merge tag 'irqchip-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core
Pull irqchip updates from Marc Zyngier:
- Add new infrastructure to stop gpiolib from rewriting irq_chip
structures behind our back. Convert a few of them, but this will
obviously be a long effort.
- A bunch of GICv3 improvements, such as using MMIO-based invalidations
when possible, and reducing the amount of polling we perform when
reconfiguring interrupts.
- Another set of GICv3 improvements for the Pseudo-NMI functionality,
with a nice cleanup making it easy to reason about the various
states we can be in when an NMI fires.
- The usual bunch of misc fixes and minor improvements.
