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" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (34 commits) iommu/dma-iommu: Remove iommu_dma_map_msi_msg() irqchip/gic-v3-mbi: Don't map the MSI page in mbi_compose_m{b, s}i_msg() irqchip/ls-scfg-msi: Don't map the MSI page in ls_scfg_msi_compose_msg() irqchip/gic-v3-its: Don't map the MSI page in its_irq_compose_msi_msg() irqchip/gicv2m: Don't map the MSI page in gicv2m_compose_msi_msg() iommu/dma-iommu: Split iommu_dma_map_msi_msg() in two parts genirq/msi: Add a new field in msi_desc to store an IOMMU cookie arm64: arch_k3: Enable interrupt controller drivers irqchip/ti-sci-inta: Add msi domain support soc: ti: Add MSI domain bus support for Interrupt Aggregator irqchip/ti-sci-inta: Add support for Interrupt Aggregator driver dt-bindings: irqchip: Introduce TISCI Interrupt Aggregator bindings irqchip/ti-sci-intr: Add support for Interrupt Router driver dt-bindings: irqchip: Introduce TISCI Interrupt router bindings gpio: thunderx: Use the default parent apis for {request,release}_resources genirq: Introduce irq_chip_{request,release}_resource_parent() apis firmware: ti_sci: Add helper apis to manage resources firmware: ti_sci: Add RM mapping table for am654 firmware: ti_sci: Add support for IRQ management firmware: ti_sci: Add support for RM core ops ...
