Subject: [PATCH v6 1/7] irq/irq_sim: add irq_set_type() callback
Date: Tue, 19 Feb 2019 17:06:44 +0100 [thread overview]
Message-ID: <20190219160650.9614-2-brgl@bgdev.pl> (raw)
In-Reply-To: <20190219160650.9614-1-brgl@bgdev.pl>
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.
