H A Dimx.cdb1a9b55 Mon Dec 12 21:23:48 CST 2011 Fabio Estevam <festevam@gmail.com> tty: serial: imx: Allow UART to be a source for wakeup

Allow UART to be a source for wakeup from low power mode.

Tested on a MX27PDK by doing:

echo enabled > /sys/devices/platform/imx21-uart.0/tty/ttymxc0/power/wakeup

echo mem > /sys/power/state

and then pressing a key in the console will wakeup the sytem.
