  • 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!

  • fcd3c5bee   irqchip/versatile: Consolidate chained IRQ handler install/remove ... Browse Code »

    Chained irq handlers usually set up handler data as well. We now have
    a function to set both under irq_desc->lock. Replace the two calls
    with one.

  • 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.

  • 59318461c   irqchip: versatile-fpga: add support for arm,versatile-sic ... Browse Code »

    The secondary controller on ARM Versatile AB and PB is similar to
    other ARM platforms, but has a pass-thru register to connect some
    interrupts directly to interrupt inputs on the primary interrupt
    controller. The PIC_ENABLES register needs to be configured for
    proper operation when the matching node is arm,versatile-sic. Add the
    the necessary IRQCHIP_DECLARE as well.

    Add support for initialization using IRQCHIP_DECLARE. This also requires
    that the controller initialization set the handle_irq function pointer
    itself when it is a primary controller.

  • d94ea3f6d   irqchip: Return -EPERM for reserved IRQs ... Browse Code »

    The irqdomain core will report a log message for any attempted map call
    that fails unless the error code is -EPERM. This patch changes the
    Versatile irq controller drivers to use -EPERM because it is normal for
    a subset of the IRQ inputs to be marked as reserved on the various
    Versatile platforms.
