If no channels are enabled when we run generic_buffer on a device, add a command-line option to just enable all of them, run the sampling and disable them all again afterwards. This is extremely useful when I'm low-level testing my sensors with interrupts and triggers, sample session: root@Ux500:/ lsiio Device 000: lsm303dlh_accel Device 001: lis331dl_accel Device 002: l3g4200d Device 003: lsm303dlh_magn Device 004: lps001wp Trigger 000: lsm303dlh_accel-trigger Trigger 001: lis331dl_accel-trigger Trigger 002: l3g4200d-trigger root@Ux500:/ generic_buffer -a -c 10 -n l3g4200d iio device number being used is 2 iio trigger number being used is 2 No channels are enabled, enabling all channels Enabling: in_anglvel_x_en Enabling: in_anglvel_y_en Enabling: in_anglvel_z_en Enabling: in_timestamp_en /sys/bus/iio/devices/iio:device2 l3g4200d-trigger -3.593664 -0.713133 4.870143 946684863662292480 3.225546 0.867357 -4.945878 946684863671875000 -0.676413 0.127296 0.106641 946684863681488037 -0.661113 0.110160 0.128826 946684863690673828 -0.664173 0.113067 0.123471 946684863700683593 -0.664938 0.109395 0.124848 946684863710144042 -0.664173 0.110619 0.130203 946684863719512939 -0.666162 0.111231 0.132651 946684863729125976 -0.668610 0.111690 0.130662 946684863738739013 -0.660501 0.110466 0.131733 946684863748565673 Disabling: in_anglvel_x_en Disabling: in_anglvel_y_en Disabling: in_anglvel_z_en Disabling: in_timestamp_en Pure awesomeness. If some channels have been enabled through scripts or manual interaction, nothing happens.
