Subject: ARM: ux500: Reprogram timers upon resume
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bb219dba0d1e46324ea462ba42f6fd8e9b7471de;p=linux-beck.git

ARM: ux500: Reprogram timers upon resume

On ux500 the MTU timer blocks are powered off during
suspend/resume, so these need some reinitialization when
coming back from suspend.
