The Intel visual sensing controller (IVSC) device is designed to control the camera sharing between host IPU for media usage and IVSC for context sensing (face detection). IVSC is exposed to HOST as an SPI device and the message protocol over the SPI BUS for communicating with the IVSC device is implemented. This is the backend of mei framework for IVSC device, which usually handles the hardware data transfer. The mei_csi and mei_ace are the clients of IVSC mei framework. The firmware downloading for the IVSC device is implemented as well.

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 Restructured Text 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.
