From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> This control on the gain of a measurement used for time of flight sensing is standard but the expected values for different enviroments may not be. As we cannot have the same ABI element documented in two files, add a generic version to sysfs-bus-iio-proximity and a note on the expected value vs measuring environment for the as3935.
