This patch rejiggers the i2c-hid code so that the OF (Open Firmware aka Device Tree) and ACPI support is separated out a bit. The OF and ACPI drivers are now separate modules that wrap the core module. Essentially, what we're doing here: * Make "power up" and "power down" a function that can be (optionally) implemented by a given user of the i2c-hid core. * The OF and ACPI modules are drivers on their own, so they implement probe / remove / suspend / resume / shutdown. The core code provides implementations that OF and ACPI can call into. We'll organize this so that we now have 3 modules: the old i2c-hid module becomes the "core" module and two new modules will depend on it, handling probing the specific device. As part of this work, we'll remove the i2c-hid "platform data" concept since it's not needed.

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.
