 *                      the n-target value for the smartreflex module.
 * @sr_errminlimit:     Error min limit value for smartreflex. This value
 *                      differs at differnet opp and thus is linked
 *                      with voltage.
 * @vp_errorgain:       Error gain value for the voltage processor. This
 *                      field also differs according to the voltage/opp.
