OMAP3530 TRM section 7.4.4.4.2 requires OFFOUTENABLE to be set (active low)
if wakeup capabilities are enabled on a pad. During OFF mode testing
on OMAP3530 EVM, it was observed that the device was not residing in
the OFF state. The device enters into the OFF state and immediately exits
from that state as if an IO wakeup event has occured. The issue was traced
down to the pad configuration of wkaeup enabled pad's.
Also, the pad configuration is included only if the respective drivers are
enabled in the defconfig.
