  • 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!

  • 22890b0db   irqchip/tb10x: 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.

    Search and conversion was done with coccinelle:

    expression E1, E2, E3;

  • 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.

  • 332fd7c4f   genirq: Generic chip: Change irq_reg_{readl,writel} arguments ... Browse Code »

    Pass in the irq_chip_generic struct so we can use different readl/writel
    settings for each irqchip driver, when appropriate. Compute
    (gc->reg_base + reg_offset) in the helper function because this is pretty
    much what all callers want to do anyway.

    Compile-tested using the following configurations:

    at91_dt_defconfig (CONFIG_ATMEL_AIC_IRQ=y)
    sama5_defconfig (CONFIG_ATMEL_AIC5_IRQ=y)
    sunxi_defconfig (CONFIG_ARCH_SUNXI=y)

    tb10x (ARC) is untested.
