Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Ingo Molnar: "Most of the IRQ subsystem changes in this cycle were irq-chip driver updates: - Qualcomm PDC wakeup interrupt support - Layerscape external IRQ support - Broadcom bcm7038 PM and wakeup support - Ingenic driver cleanup and modernization - GICv3 ITS preparation for GICv4.1 updates - GICv4 fixes There's also the series from Frederic Weisbecker that fixes memory ordering bugs for the irq-work logic, whose primary fix is to turn work->irq_work.flags into an atomic variable and then convert the complex (and buggy) atomic_cmpxchg() loop in irq_work_claim() into a much simpler atomic_fetch_or() call. There are also various smaller cleanups" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (44 commits) pinctrl/sdm845: Add PDC wakeup interrupt map for GPIOs pinctrl/msm: Setup GPIO chip in hierarchy irqchip/qcom-pdc: Add irqchip set/get state calls irqchip/qcom-pdc: Add irqdomain for wakeup capable GPIOs irqchip/qcom-pdc: Do not toggle IRQ_ENABLE during mask/unmask irqchip/qcom-pdc: Update max PDC interrupts of/irq: Document properties for wakeup interrupt parent genirq: Introduce irq_chip_get/set_parent_state calls irqdomain: Add bus token DOMAIN_BUS_WAKEUP genirq: Fix function documentation of __irq_alloc_descs() irq_work: Fix IRQ_WORK_BUSY bit clearing irqchip/ti-sci-inta: Use ERR_CAST inlined function instead of ERR_PTR(PTR_ERR(...)) irq_work: Slightly simplify IRQ_WORK_PENDING clearing irq_work: Fix irq_work_claim() memory ordering irq_work: Convert flags to atomic_t irqchip: Ingenic: Add process for more than one irq at the same time. irqchip: ingenic: Alloc generic chips from IRQ domain irqchip: ingenic: Get virq number from IRQ domain irqchip: ingenic: Error out if IRQ domain creation failed irqchip: ingenic: Drop redundant irq_suspend / irq_resume functions ...
