Merge tag 'irqchip-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core
Pull irqchip updates frim Marc Zyngier:
- More APCI fixes and improvements for the LoongArch architecture,
adding support for the HTVEC irqchip, suspend-resume, and some
PCI INTx workarounds
- Initial DT support for LoongArch. I'm not even kidding.
- Support for the MTK CIRQv2, a minor deviation from the original version
- Error handling fixes for wpcm450, GIC...
- BE detection for a FSL controller
- Declare the Sifive PLIC as wake-up agnostic
- Simplify fishing out the device data for the ST irqchip
- Mark some data structures as __initconst in the apple-aic driver
- Switch over from strtobool to kstrtobool
- COMPILE_TEST fixes
