This patch introduces a new driver to support the Goodix GT7986U touch controller. This device is not compatible with Microsoft's HID-over-SPI protocol and therefore needs to implement its own flavor. The data reported is packaged according to the HID protocol but uses SPI for communication to improve speed. This enables the device to transmit not only coordinate data but also corresponding raw data that can be accessed by user-space programs through the hidraw interface. The raw data can be utilized for functions like palm rejection, thereby improving the touch experience. Key features: - Device connection confirmation and initialization - IRQ-based event reporting to the input subsystem - Support for HIDRAW operations (GET_REPORT and SET_REPORT) Reviewed-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Charles Wang <charles.goodix@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
