Subject: [PATCH v22 05/11] clocksource: arm_arch_timer: introduce some new structs to prepare for GTDT
Date: Wed, 22 Mar 2017 00:31:16 +0800 [thread overview]
Message-ID: <20170321163122.9183-6-fu.wei@linaro.org> (raw)
In-Reply-To: <20170321163122.9183-1-fu.wei@linaro.org>
From: Fu Wei <fu.wei@linaro.org>
The patch introduce two new structs: arch_timer_mem, arch_timer_mem_frame.
And also introduce a new define: ARCH_TIMER_MEM_MAX_FRAMES
These will be used for refactoring the memory-mapped timer init code to
prepare for GTDT
