Merge tag 'irq-core-2024-01-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq subsystem updates from Ingo Molnar:

 - Add support for the IA55 interrupt controller on RZ/G3S SoC's

 - Update/fix the Qualcom MPM Interrupt Controller driver's register
   enumeration within the somewhat exotic "RPM Message RAM" MMIO-mapped
   shared memory region that is used for other purposes as well

 - Clean up the Xtensa built-in Programmable Interrupt Controller driver
   (xtensa-pic) a bit
