The Multi Timer Unit (MTU) is currently used as clocksource and sched_clk for the u8500 machine. The MTU block loose power during cpuidle sleep states so an alternate clocksource is needed and these patches adds the db8500 PRCMU timer.
Mattias Wallin (3): plat-nomadik: MTU sched_clock as a config option clocksource: add DB8500 PRCMU Timer support mach-ux500: Initialize the DB8500 PRCMU timer
