+ * struct input_absinfo - used by EVIOCGABS/EVIOCSABS ioctls
+ * @value: latest reported value for the axis.
+ * @minimum: specifies minimum value for the axis.
+ * @maximum: specifies maximum value for the axis.
+ * @fuzz: specifies fuzz value that is used to filter noise from
+ *     the event stream.
+ * @flat: values that are within this value will be discarded by
+ *     joydev interface and reported as 0 instead.
+ * @resolution: specifies resolution for the values reported for
+ *     the axis.
+ *
+ * Note that input core does not clamp reported values to the
+ * [minimum, maximum] limits, such task is left to userspace.
+ *
+ * Resolution for main axes (ABS_X, ABS_Y, ABS_Z) is reported in
+ * units per millimeter (units/mm), resolution for rotational axes
+ * (ABS_RX, ABS_RY, ABS_RZ) is reported in units per radian.
