[4/8] OMAP3: powerdomain data: add wake-up latency figures

Commit Message

Jean Pihet Sept. 2, 2011, 1:13 p.m. UTC

Figures are added to the power domains structs for RET and OFF modes.

Note: the latency figures for MPU, PER, CORE, NEON have been obtained
from actual measurements.
The latency figures for the other power domains are preliminary and
shall be added.

Tested on OMAP3 Beagleboard in RET/OFF using wake-up latency constraints
on MPU, CORE and PER.
