From: Vishwanath BS <vishwanath...@ti.com>
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 <vishwanath...@ti.com>
The INACTIVE state is added as unsupported.
Tested on OMAP4 Pandaboard in RET/OFF using wake-up latency constraints on
MPU, CORE and PER.
