Tegra194 AON GPIO controller with the use of its internal hardware timestamping engine (HTE), also known as GTE, can timestamp GPIO lines through system counter. This patch implements enable/disable callbacks for the GPIO controller. In enable call, it will set timestamp function bit and GPIO line rising/falling edges in the config register. In disable call, it restores the state. Signed-off-by: Dipen Patel <dipenp@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
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.
