Hi All,

         I tried with gpio-event from http://svn.hylands.org/linux/gpio-event/module/gpio-event-drv.c which is provide by Dave Hylands , it gives me the put 

./daveuser 156:b:2000

# cat /proc/gpio-event/pins

GPIO: 156 Edge: Both    Debounce: 208 msec

./daveuser 156:f:2000

# cat /proc/gpio-event/pins

GPIO: 156 Edge: Falling Debounce: 208 msec

# ./daveuser 156:r:2000

# cat /proc/gpio-event/pins

GPIO: 156 Edge: Rising  Debounce: 208 msec
