Subject: [PATCH] clocksource/arm_arch_timer: Map frame with of_io_request_and_map()
Date: Fri, 4 Mar 2016 09:56:09 -0800 [thread overview]
Message-ID: <1457114169-16301-1-git-send-email-sboyd@codeaurora.org> (raw)
Let's use the of_io_request_and_map() API so that the frame
region is protected and shows up in /proc/iomem.
