Date: Sat, 28 Mar 2015 15:23:35 +0530 [thread overview]
Message-ID: <1427536418-22801-3-git-send-email-deepak.s@linux.intel.com> (raw)
In-Reply-To: <1427536418-22801-1-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.
