Subject: [PATCH 5/7] OMAP3: RX-51: Pass cpu idle parameters
Date: Wed, 17 Feb 2010 18:02:28 -0600 [thread overview]
Message-ID: <1266451350-4480-6-git-send-email-khilman@deeprootsystems.com> (raw)
In-Reply-To: <1266451350-4480-1-git-send-email-khilman@deeprootsystems.com>
From: Kalle Jokiniemi <kalle.jokiniemi@digia.com>
Pass cpuidle parameters for RX-51. Numbers based on
measurements made in October 2009 for PM optimized
kernel with CPU freq enabled. Assumes OPP2 (main
idle OPP, and worst case latencies).
