Rasmus Villemoes says: ==================== dt-bindings: dp83867: add binding for io_impedance_ctrl nvmem cell We have a board where measurements indicate that the current three options - leaving IO_IMPEDANCE_CTRL at the reset value (which is factory calibrated to a value corresponding to approximately 50 ohms) or using one of the two boolean properties to set it to the min/max value - are too coarse. This series adds a device tree binding for an nvmem cell which can be populated during production with a suitable value calibrated for each board, and corresponding support in the driver. The second patch adds a trivial phy wrapper for dev_err_probe(), used in the third. ==================== Link: https://lore.kernel.org/r/20220614084612.325229-1-linux@rasmusvillemoes.dk Signed-off-by: Jakub Kicinski <kuba@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 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.
