Subject: [PATCH v2 7/7] OMAP: PM CONSTRAINTS: add power domains wake-up latency figures
Date: Thu, 10 Mar 2011 18:47:27 +0100 [thread overview]
Message-ID: <1299779247-20511-8-git-send-email-j-pihet@ti.com> (raw)
In-Reply-To: <1299779247-20511-1-git-send-email-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>
