Subject: [PATCH 3/3] OMAP: RX-51: Pass cpu idle parameters
Date: Thu, 29 Oct 2009 10:30:20 +0200 [thread overview]
Message-ID: <1256805020-7402-4-git-send-email-kalle.jokiniemi@digia.com> (raw)
In-Reply-To: <1256805020-7402-3-git-send-email-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).
