Input: sentelic - enabling absolute coordinates output for newer hardware
- Hooking multi-finger coordinates output with kernel multitouch library; - Enabling absolute coordinates output for Cx+ hardware. The older hardware performs much better in relative mode; thus relative mode related code are preserved. Part of the code is based on the work done by Oskari Saarenmaa <os@ohmu.fi>, which was used to support the clickpad found on ASUS UX21/31 Ultrabook. On the other hand, the FSP found on UX21/31 doesn't have hardware capability register other than PnP ID, which means that we'll have to figure out an alternative approach to identify such pad correctly; otherwise, blindly adding INPUT_PROP_BUTTONPAD property may compatability issues amongst existing FSPs.
