Subject: [PATCH 1/2] gpio: rcar: set IRQ chip parent_device
Date: Thu, 8 Dec 2016 18:32:27 +0100 [thread overview]
Message-ID: <20161208173228.16835-2-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20161208173228.16835-1-niklas.soderlund+renesas@ragnatech.se>
This enables Runtime PM handling for interrupts.
By setting the parent_device in struct irq_chip genirq will call the
pm_runtime_get/put APIs when an IRQ is requested/freed.
