The i2c subsystem was enhanced circa 2015 to support operating as an i2c-slave device. Prior to that, the i2c-pxa driver supported an i2c-slave but had its own APIs. There are no existing in-kernel drivers or platforms that utilize the i2c-pxa APIs. Migrate the i2c-pxa driver to the general i2c-slave APIs so that existing drivers, such as the i2c-slave-eeprom, can be used. This has been tested with a Marvell EspressoBin, using i2c-pxa and i2c-slave-eeprom, acting as a slave, and a RaspeberryPi 3, using the at24 driver, acting as a master.

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.
