	The rmi_f11 driver currently disables dribble packets and the palm detect gesture for all devices. This patch creates a parameter in the 2d sensor platform data for controlling this functionality on a per device basis. For more information on dribble packets: Commit05ba999fca("HID: rmi: disable dribble packets on Synaptics touchpads") For more information on the palm detect gesture: Commitf097deef59("HID: rmi: disable palm detect gesture when present") Signed-off-by: Andrew Duggan <aduggan@synaptics.com> Reviewed-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
