Subject: [PATCH v2 2/2] irqchip: sunxi-nmi: switch to of_io_request_and_map() from of_iomap()
Date: Tue, 6 Oct 2015 00:42:14 +0800 [thread overview]
Message-ID: <1444063334-19832-3-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1444063334-19832-1-git-send-email-wens@csie.org>
Switch to the new of_io_request_and_map() call, so the IO resource is
properly held, and also shows up in /proc/iomem.
