Hmm, prescalers seem common enough among counter devices to permit these attributes to be listed in the sysfs-bus-counter documentation file. However, I'd like to wait until we get another counter driver for a device with a prescaler before we make that move. From there, we'll have a better vantage point to determine a fitting standard prescaler attribute behavior. So for now, we'll keep these attributes documented here in the sysfs-bus-counter-ftm-quaddec file, until the time comes to broach the discussion again. William Breathitt Gray
