  • d17cab445   irqchip: Kill off set_irq_flags usage ... Browse Code »

    set_irq_flags is ARM specific with custom flags which have genirq
    equivalents. Convert drivers to use the genirq interfaces directly, so we
    can kill off set_irq_flags. The translation of flags is as follows:

    IRQF_VALID -> !IRQ_NOREQUEST
    IRQF_PROBE -> !IRQ_NOPROBE
    IRQF_NOAUTOEN -> IRQ_NOAUTOEN

    For IRQs managed by an irqdomain, the irqdomain core code handles clearing
    and setting IRQ_NOREQUEST already, so there is no need to do this in
    .map() functions and we can simply remove the set_irq_flags calls. Some
    users also modify IRQ_NOPROBE and this has been maintained although it
    is not clear that is really needed. There appears to be a great deal of
    blind copy and paste of this code.

  • bd0b9ac40   genirq: Remove irq argument from irq flow handlers ... Browse Code »

    Most interrupt flow handlers do not use the irq argument. Those few
    which use it can retrieve the irq number from the irq descriptor.

    Remove the argument.

    Search and replace was done with coccinelle and some extra helper
    scripts around it. Thanks to Julia for her help!

  • 41a83e06e   irqchip: Prepare for local stub header removal ... Browse Code »

    The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
    the local irqchip.h became an empty shell, which solely includes
    include/linux/irqchip.h

    Include the global header in all irqchip drivers instead of the local
    header, so we can remove it.

  • 9414b6e2d   irq: irq-keystone: Fix race in installing chained IRQ handler ... Browse Code »

    Fix a race where a pending interrupt could be received and the handler
    called before the handler's data has been setup, by converting to
    irq_set_chained_handler_and_data().

  • 89323f8c5   irqchip: keystone: Add irq controller ip driver ... Browse Code »

    On Keystone SOCs, DSP cores can send interrupts to ARM
    host using the IRQ controller IP. It provides 28 IRQ
    signals to ARM. The IRQ handler running on HOST OS can
    identify DSP signal source by analyzing SRCCx bits in
    IPCARx registers. This is one of the component used by
    the IPC mechanism used on Keystone SOCs.
