Date: Sat, 1 Apr 2017 01:51:00 +0800 [thread overview] Message-ID: <20170331175105.8370-7-fu.wei@linaro.org> (raw) In-Reply-To: <20170331175105.8370-1-fu.wei@linaro.org> From: Fu Wei <fu.wei@linaro.org> Currently the code to probe MMIO architected timers mixes DT parsing with actual poking of hardware. This makes the code harder than necessary to understand, and makes it difficult to add support for probing via ACPI. This patch factors all the DT-specific logic out of arch_timer_mem_init(), into a new function arch_timer_mem_of_init(). The former pokes the hardware and determines the suitablility of frames based on a datastructure populated by the latter. This cleanly separates the two and will make it possible to add probing using the ACPI GTDT in subsequent patches.
