Subject: [PATCH 09/13] OMAP3: powerdomain data: add wake-up latency figures
Date: Thu, 28 Jul 2011 10:30:16 +0200 [thread overview]
Message-ID: <1311841821-10252-10-git-send-email-j-pihet@ti.com> (raw)
In-Reply-To: <1311841821-10252-1-git-send-email-j-pihet@ti.com>
From: Jean Pihet <j-pihet@ti.com>
Figures are added to the power domains structs.
Note: the figures are preliminary figures. More accurate measurements
are needed. Also the conditions of measurements shall be investigated
and described.
Tested on OMAP3 Beagleboard in RET/OFF using wake-up latency constraints
on MPU, CORE and PER.
Signed-off-by: Jean Pihet <j-pihet@ti.com>
