This change adds debugfs to read and write temperature sensor coefficients - g, h, j and cal5. The coefficients can vary between product and product, so it can be very useful to be able to modify them on the fly during the calibration process. e.g.: cat /sys/kernel/debug/940f23d0000.pvt/ts_coeff_cal5 4096 echo 83000 > sys/kernel/debug/940f23d0000.pvt/ts_coeff_g Signed-off-by: Eliav Farber <farbere@amazon.com> Link: https://lore.kernel.org/r/20220908152449.35457-21-farbere@amazon.com Signed-off-by: Guenter Roeck <linux@roeck-us.net>
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.
