From 838a2ae80a6ab52139fb1bf0a93ea8c5eff94488 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Sat, 12 Jan 2013 11:50:05 +0000 Subject: ARM: use clockevents_config_and_register() where possible The clockevent core is able to figure out the best mult and shift, calculate min_delta_ns and max_delta_ns, with the necessary info passed into clockevents_config_and_register(). Use this combined configure and register function where possible to make the codes less error prone and gain some positive diff stat.
