Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull IRQ chip updates from Ingo Molnar:
 "A late irqchips update:

   - New TI INTR/INTA set of drivers

   - Rewrite of the stm32mp1-exti driver as a platform driver

   - Update the IOMMU MSI mapping API to be RT friendly

   - A number of cleanups and other low impact fixes"
