On SAM9X60, slewrate should be enabled on pins with a switching frequency below 50Mhz. Since most of our pins do not exceed this value, we enable slewrate by default. Pins with a switching value that exceeds 50Mhz will have to explicitly disable slewrate. This patch changes the ABI. However, the slewrate macros are only used by SAM9X60 and, at this moment, there are no device-tree files available for this platform.

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.
