iio: event_monitor: Enable events before monitoring
After some painful sessions with a driver that register an
enable/disable sysfs knob (gp2ap002) and manually going
in and enabling the event before monitoring it:
cd /sys/bus/iio/devices/iio\:device2/events
# ls
in_proximity_thresh_either_en
# echo 1 > in_proximity_thresh_either_en
I realized that it's better if the iio_event_monitor is
smart enough to enable all events by itself and disable them
after use, if passed the -a flag familiar from the
iio_generic_buffer tool.
Auto-enabling events depend on the hardware being able
to handle all events at the same time which isn't
necessarily the case, so a command line option is required
for this.
