'irq_sim_domain'
File headers are not good candidates for kerneldoc.
Fixes the following W=1 kernel build warning(s):
drivers/iio/dummy/iio_dummy_evgen.c:30: warning: Cannot understand * @regs: irq regs we are faking
on line 30 - I thought it was a doc line
drivers/iio/dummy/iio_dummy_evgen.c:42: warning: Function parameter or member 'irq_sim_domain' not described in 'iio_dummy_eventgen'

We need to preserve the "iio_evgen->irq_sim_domain" error code before
we free "iio_evgen" otherwise it leads to a use after free.

The interrupt simulator API exposes a lot of custom data structures and
functions and doesn't reuse the interfaces already exposed by the irq
subsystem. This patch tries to address it.
We hide all the simulator-related data structures from users and instead
rely on the well-known irq domain. When creating the interrupt simulator
the user receives a pointer to a newly created irq_domain and can use it
to create mappings for simulated interrupts.
It is also possible to pass a handle to fwnode when creating the simulator
domain and retrieve it using irq_find_matching_fwnode().
The irq_sim_fire() function is dropped as well. Instead we implement the
irq_get/set_irqchip_state interface.
We modify the two modules that use the simulator at the same time as
adding these changes in order to reduce the intermediate bloat that would
result when trying to migrate the drivers in separate patches.

The memory allocated in the function iio_dummy_evgen_create is not
released if it fails to add the evgen device to device hierarchy. This
may result in a memory leak bug.

As discussed with Marc Zyngier: irq_sim_init() and its devres variant
should return the base of the allocated interrupt range on success
rather than 0. This will be modified later - first, change the way
users handle the return value of these routines.

This patch moves the reference IIO dummy driver from drivers/staging/iio
into a separate folder, drivers/iio/dummy and adds the proper Kconfig
and Makefile for it.
A new config menu entry called IIO dummy driver has also been added
in the Industrial I/O support menu, corresponding to this driver.
