[PATCH 11/15] OMAP3: powerdomain data: add wake-up latency figures

From: <hidden>
Date: 2011-08-11 15:07:53
Subsystem: arm port, omap2+ support, the rest · Maintainers: Russell King, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Linus Torvalds

From: Jean Pihet <redacted>

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.
