[PATCH 0/3] simulated interrupts

[Bartosz Golaszewski <brgl@xxxxxxxx>]

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.
