Subject: [PATCH 5/5] ARM: tegra: cpuidle: use firmware call for power down
Date: Tue, 21 Jan 2014 19:10:16 +0900 [thread overview]
Message-ID: <1390299016-14105-6-git-send-email-acourbot@nvidia.com> (raw)
In-Reply-To: <1390299016-14105-1-git-send-email-acourbot@nvidia.com>
Invoke the do_idle() firmware call before suspending a CPU so that the
underlying firmware (if any) can take necessary action.
