From e2c501190c7d4bf9d7febb9e1f1094cbde59ed89 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Tue, 30 Oct 2012 11:17:01 +0000 Subject: [PATCH] arm: Use generic timer broadcast receiver Currently, the ARM backend must maintain a redundant list of timers for the purpose of centralising timer broadcast functionality. This prevents sharing timer drivers across architectures. This patch moves the pain of dealing with timer broadcasts to the core clockevents tick broadcast code, which already maintains its own list of timers.
