Date: Thu, 26 Feb 2015 20:46:55 +0530 [thread overview]
Message-ID: <1424963818-11931-3-git-send-email-deepak.s@linux.intel.com> (raw)
In-Reply-To: <1424963818-11931-1-git-send-email-deepak.s@linux.intel.com>
From: Deepak S <deepak.s@linux.intel.com>
After feedback from the hardware team we are changing the RC6
promotional timer to increase the power saving without
changing performance.
