From 0d152c27e336b5fd777da7dd3e814617e7305afd Mon Sep 17 00:00:00 2001 From: Yi Li Date: Mon, 28 Dec 2009 10:21:49 +0000 Subject: Blackfin: SMP: make core timers per-cpu clock events for HRT SMP systems require per-cpu local clock event devices in order to enable HRT support. One a BF561, we can use local core timer for this purpose. Originally, there was one global core-timer clock event device set up for core A. To accomplish this feat, we need to split the gptimer0/core timer logic so that each is a standalone clock event. There is no requirement that we only have one clock event source anyways. Once we have this, we just define per-cpu clock event devices for each local core timer.
