I have noticed that after resume cpu starts entering idle states

	grep . /sys/devices/system/cpu/cpu0/cpuidle/state?/usage

and after:

	echo 0 > /sys/devices/platform/omap/omap_uart.0/sleep_timeout
	echo 0 > /sys/devices/platform/omap/omap_uart.1/sleep_timeout
	echo 0 > /sys/devices/platform/omap/omap_uart.2/sleep_timeout
	echo 0 > /sys/devices/platform/omap/omap_uart.3/sleep_timeout

lcd starts working again. So this is what i am using for suspend now:

	echo 1 > /sys/devices/platform/omapfb/graphics/fb0/blank
	echo mem > /sys/power/state
	echo 0 > /sys/devices/platform/omap/omap_uart.0/sleep_timeout
	echo 0 > /sys/devices/platform/omap/omap_uart.1/sleep_timeout
	echo 0 > /sys/devices/platform/omap/omap_uart.2/sleep_timeout
	echo 0 > /sys/devices/platform/omap/omap_uart.3/sleep_timeout
	echo 0 > /sys/devices/platform/omapfb/graphics/fb0/blank
