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
