Use the introduced functionality to read firmware files and flash their
contents into the device's internal flash memory to implement the devlink
flash update callback.
Sample output on EDS2 development board:
# devlink -j dev info i2c/1-0070 | jq '.[][]["versions"]["running"]'
{
"fw": "6026"
}
# devlink dev flash i2c/1-0070 file firmware_fw2.hex

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.
