Change Contact to "linux-iio@vger.kernel.org" since this ABI is available for all Counter drivers. Since num_overflows can be reset, replace the "since count Y start" phrase with "of Count Y" instead. > What: /sys/bus/counter/devices/counterX/countY/ceiling_component_id > What: /sys/bus/counter/devices/counterX/countY/floor_component_id > What: /sys/bus/counter/devices/counterX/countY/count_mode_component_id > @@ -219,11 +225,13 @@ What: /sys/bus/counter/devices/counterX/countY/prescaler_component_id > What: /sys/bus/counter/devices/counterX/countY/preset_component_id > What: /sys/bus/counter/devices/counterX/countY/preset_enable_component_id > What: /sys/bus/counter/devices/counterX/countY/signalZ_action_component_id > +What: /sys/bus/counter/devices/counterX/countY/num_overflows_component_id > What: /sys/bus/counter/devices/counterX/signalY/cable_fault_component_id > What: /sys/bus/counter/devices/counterX/signalY/cable_fault_enable_component_id > What: /sys/bus/counter/devices/counterX/signalY/filter_clock_prescaler_component_id > What: /sys/bus/counter/devices/counterX/signalY/index_polarity_component_id > What: /sys/bus/counter/devices/counterX/signalY/synchronous_mode_component_id > +What: /sys/bus/counter/devices/counterX/signalY/frequency_component_id > KernelVersion: 5.16 > Contact: linux-iio@vger.kernel.org > Description: > @@ -364,3 +372,9 @@ Description: > via index_polarity.
