Subject: [PATCHv2 0/3] clocksource: add db8500 PRCMU timer
Date: Thu, 2 Jun 2011 11:34:31 +0200 [thread overview]
Message-ID: <1307007271-1004-1-git-send-email-mattias.wallin@stericsson.com> (raw)
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
