[PATCH 08/11] ARM: ux500: convert timer suspend/resume to clock_event_device
From: Stephen Warren <hidden>

From: Stephen Warren <redacted> 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.
