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
