Merge tag 'irqchip-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Pull irqchip updates from Marc Zyngier:

 - Revamped the irqdomain internals to consistently cache irqdata

 - Expose a new API to simplify IRQ handling involving an irqdomain by
   not using the IRQ number

 - Convert all the irqchip drivers to this new API

 - Allow the Qualcomm PDC driver to be compiled as a module

 - Fix HiSi MBIGEN compile warning when CONFIG_ACPI isn't selected

 - Remove a bunch of spurious printks on error paths

 - The obligatory couple of DT updates
