Input: synaptics - add support for reporting x/y resolution
Synaptics uses anisotropic coordinate system. On some wide touchpads vertical resolution can be twice as high as horizontal which causes unequal sensitivity on x/y directions. Add support for reading the resolution with EVIOCGABS ioctl. Signed-off-by: Tero Saarni <tero.saarni@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
