Rework the read and write code paths in the driver to support operation in atomic contexts in master mode. This change does not apply to slave mode because there is no way to handle interruptions in that context. Adjust the message timeout to include some extra time. For non-atomic contexts, 500 ms is added to the timeout. For atomic contexts, 2000 ms is added because transfers happen in polled mode, requiring more time to account for the polling overhead. Similar changes have been implemented in other drivers, including: commit3a5ee18d2a("i2c: imx: implement master_xfer_atomic callback") commit445094c8a9("i2c: exynos5: add support for atomic transfers") commitede2299f71("i2c: tegra: Support atomic transfers") commitfe402bd090("i2c: meson: implement the master_xfer_atomic callback") Signed-off-by: Manikanta Guntupalli <manikanta.guntupalli@amd.com> Reviewed-by: Andi Shyti <andi.shyti@kernel.org> Signed-off-by: Andi Shyti <andi.shyti@kernel.org>
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.
