Say Y here to support PXA930 Trackball mouse.
config MOUSE_MAPLE
tristate "Maple mouse (for the Dreamcast)"
depends on MAPLE
help
This driver supports the Maple mouse on the SEGA Dreamcast.
Most Dreamcast users, who have a mouse, will say Y here.
To compile this driver as a module choose M here: the module will be
called maplemouse.
