Subject: [PATCH 0/2] irq/irq_sim: try to improve the API

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

Currently the interrupt simulator exposes structures that don't need
to be public and has a helper that manually maps the simulator's irq
offsets to the global interrupt numberspace - something that should
be preferably handles by an irq_domain.

The first patch addresses the public structures: it moves them into
the relevant .c file and makes the init function return an opaque
pointer.

The second patch adds a linear irq_domain to the simulator and removes
the irq_sim_irqnum() routine. Users should now use the standard
irq_domain functions.

Both users of the irq_sim are converted at the same time as it's much
easier than trying to transition them step by step.

Tested both the gpio-mockup module as well as the iio_dummy_evgen.

Bartosz Golaszewski (2):
  irq/irq_sim: make the irq_sim structure opaque
  irq/irq_sim: use irq domain
