The safest quirk for a device (the one that works out of the box for
most of them) is the MT_QUIRK_NOT_SEEN_MEANS_UP. Indeed, it does not
make any assumption on the device. When adding a new device, we can
easily test it against MT_CLS_DEFAULT, and then optimize it with other
quirks: that's why no device use MT_CLS_DEFAULT right now.
This patch introduce also MT_CLS_DUAL_DEFAULT which has the same purpose
than MT_CLS_DEFAULT, but for dual touch panels.
Finally, the patch renames MT_CLS_DUAL1 to MT_CLS_DUAL_INRANGE_CONTACTID
and MT_CLS_DUAL2 to MT_CLS_DUAL_INRANGE_CONTACTNUMBER for better
readability.
