Subject: [PATCH] TESTING HACKHACK: add dummy virt-consumer for OMAP3/4/5

Set CONFIG_REGULATOR_VIRTUAL_CONSUMER=y to use

OMAP3630(beagle-XM):
MPU :
REG=/sys/class/regulator/regulator.9
CONS=/sys/devices/platform/reg-virt-consumer.0

for V in 1012500 1200000 1325000 1375000
do
	echo -n "$V">$CONS/min_microvolts
	echo -n "$V">$CONS/max_microvolts
	echo "Tried $V, Voltage =" `cat $REG/microvolts`
done

OMAP4460(Panda-ES): MPU: http://pastebin.com/TKPPZDQ1
REG=/sys/class/regulator/regulator.1
CONS=/sys/devices/platform/reg-virt-consumer.0

for V in 1025000 1200000 1313000 1375000 1389000
do
	echo -n "$V">$CONS/min_microvolts
	echo -n "$V">$CONS/max_microvolts
	echo "Tried $V, Voltage =" `cat $REG/microvolts`
done

IVA:
REG=/sys/class/regulator/regulator.2
CONS=/sys/devices/platform/reg-virt-consumer.1

for V in 950000 1140000 1291000 1375000 1376000

do
	echo -n "$V">$CONS/min_microvolts
	echo -n "$V">$CONS/max_microvolts
	echo "Tried $V, Voltage =" `cat $REG/microvolts`
done

OMAP5: Similarly
