 * (touchscreen).  This is useful when F11_2D_QUERY14 register is not
 * available.
 * @disable_report_mask - Force data to not be reported even if it is supported

 * @topbuttonpad - Used with the "5 buttons touchpads" found on the Lenovo 40
 * series
 * @kernel_tracking - most moderns RMI f11 firmwares implement Multifinger
 * Type B protocol. However, there are some corner cases where the user
 * triggers some jumps by tapping with two fingers on the touchpad.
 * Use this setting and dmax to filter out these jumps.
 * Also, when using an old sensor using MF Type A behavior, set to true to
 * report an actual MT protocol B.
 * @dmax - the maximum distance (in sensor units) the kernel tracking allows two
 * distincts fingers to be considered the same.
