Linux kernel source tree

Adapt the RTL9300 I2C controller driver to use more of the regmap API, especially make use of reg_field and regmap_field instead of macros to represent registers. Most register operations are performed through regmap_field_* API then. Handle SCL selection using separate chip-specific functions since this is already known to differ between the Realtek SoC families in such a way that this cannot be properly handled using just a different reg_field. This makes it easier to add support for newer generations or to handle differences between specific revisions within a series. Just by defining a separate driver data structure with the corresponding register field definitions and linking it to a new compatible.

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.
