Device I2C adapter is capable of writing and reading large messages. For I2C writes there is 2 methods: simple for max 2 byte messages and usb_control_msg() with payload data for larger I2C messages. Add I2C adapter logic which selects suitable method according to message size. Add also support for plain I2C read.

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.
