From mboxrd@z Thu Jan 1 00:00:00 1970 From: vincent.guittot@linaro.org (Vincent Guittot) Date: Wed, 24 Aug 2011 08:44:05 +0200 Subject: [PATCH] ARM: ux500: send cpufreq notification for all cpus Message-ID: <1314168245-2373-1-git-send-email-vincent.guittot@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The same clock is used for all cpus so we must notify the frequency change for each one in order to update the configuration of all twd clockevents.
