Subject[PATCH v6 1/7] irq/irq_sim: add irq_set_type() callback
Date
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

Implement the irq_set_type() callback and call irqd_set_trigger_type()
internally so that users interested in the configured trigger type can
later retrieve it using irqd_get_trigger_type(). We only support edge
trigger types.
