From 8726e96fcb29298351c777670742b553ca947508 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 7 Nov 2012 17:07:45 -0700 Subject: ARM: ux500: convert timer suspend/resume to clock_event_device Move ux500's timer suspend/resume functions from struct sys_timer ux500_timer into struct clock_event_device nmdk_clkevt. This will allow the sys_timer suspend/resume fields to be removed, and eventually lead to a complete removal of struct sys_timer.
