[PATCH 0/3] clocksource: add db8500 PRCMU timer
From: Mattias Wallin
Date: Tue May 31 2011 - 04:31:07 EST
These patches makes it possible to use the PRCMU timer as clocksource
for the db8500 chip. Previously the Multi Timer Unit (MTU) was used alone
but the MTU block loose power during sleep states so an alternate
clocksource is needed.
These patches also adds a configuration option to use either the MTU or the PRCMU
as the sched_clk.

plat-nomadik: MTU sched_clock as an option
clocksource: add DB8500 PRCMU Timer support
mach-ux500: add support for clocksource DB8500 PRCMU
