Marc,
as discussed. This is hopefully the last version. The irq_set_type() callback now only accepts edge triggers.
v1 -> v2: - instead of providing the irq_sim_get_type() helper, move the irq type logic into the simulator and provide a helper that allows users to specify the type of the fired interrupt
v2 -> v3: - switch back to having irq_sim_type() and put the line state logic into the GPIO testing module
v3 -> v4: - drop irq_sim_get_type() and use a notifier chain instead so that any change in type configuration can be pushed out to interested users - change the locking mechanism in gpio-mockup to a spinlock as we can't take a mutex when a hardirq-safe spinlock in irq_desc is being held when the irq_set_type() callback is called - refuse to set any other type than falling or rising edge in irq_set_config
v4 -> v5: - drop the notifier, use irqd_set_trigger_type() instead
v5 -> v6: - same as v5, but we're now validating the trigger type and only allow edge triggers
Bartosz Golaszewski (7): irq/irq_sim: add irq_set_type() callback gpio: mockup: add locking gpio: mockup: implement get_multiple() gpio: mockup: don't create the debugfs link named after the label gpio: mockup: change the type of 'offset' to unsigned int gpio: mockup: change the signature of unlocked get/set helpers gpio: mockup: rework debugfs interface
