Subject: [PATCH/RESEND] clocksource/arm_arch_timer: Map frame with of_io_request_and_map()
Date: Tue, 18 Oct 2016 16:45:14 -0700 [thread overview]
Message-ID: <20161018234514.6175-1-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.
