[10/13] OMAP4: powerdomain data: add wake-up latency figures

Commit Message

Jean Pihet July 28, 2011, 8:30 a.m. UTC

From: Vishwanath BS <[e-mail]>

This patch adds wake up latency numbers for OMAP4. Note that these are
preliminary numbers and need to be relooked.

Signed-off-by: Vishwanath BS <[e-mail]>

The INACTIVE state is added as unsupported.

Tested on OMAP4 Pandaboard in RET/OFF using wake-up latency constraints on
MPU, CORE and PER.
