    Subject[PATCH v4 0/3] simulated interrupts
    Date
    Some frameworks (e.g. iio, gpiolib) use irq_work to implement simulated
    interrupts that can be 'fired' from process context when needed and
    requested just like normal interrupts. This is useful for testing and
    development purposes.

    Currently this code is reimplemented by every user. This series
    proposes to add a new set of functions that can be used by drivers
    that want to simulate interrupts without having to duplicate any
    boilerplate code.

    The first patch adds a simple irq simulator framework. The second
    extends it with resource management. The third uses the new
    functionality in the gpio-mockup testing driver.

    NOTE: The next candidate for using this API would be iio-dummy-evgen.

    v1 -> v2:
    - added a call to irq_work_sync in irq_sim_fini()

    v2 -> v3:
    - added the license header to new files
    - added Acked-by's and Reviewed-by's

    v3 -> v4:
    - moved the .c file to kernel/irq

    Bartosz Golaszewski (3):
    irq/irq_sim: add a simple interrupt simulator framework
    irq/irq_sim: add a devres variant of irq_sim_init()
    gpio: mockup: use irq_sim
