From 0583fe478a7d93be2c814b7e50d6e81c287edfe8 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 10 Apr 2013 18:27:51 -0500 Subject: ARM: convert arm/arm64 arch timer to use CLKSRC_OF init This converts arm and arm64 to use CLKSRC_OF DT based initialization for the arch timer. A new function arch_timer_arch_init is added to allow for arch specific setup. This has a side effect of enabling sched_clock on omap5 and exynos5. There should not be any reason not to use the arch timers for sched_clock.
