The stmfts (ST-Microelectronics FingerTip S) touchscreen device is a capacitive multi-touch controller mainly for mobile use. It's connected through i2c bus at the address 0x49 and it interfaces with userspace through input event interface. At the current state it provides a touchscreen multitouch functionality up to 10 fingers. Each finger is enumerated with a distinctive id (from 0 to 9). If enabled the device can support single "touch" hovering, by providing three coordinates, x, y and distance. It is possible to select the touchkey functionality which provides a basic two keys interface for "home" and "back" menu, typical in mobile phones.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
