Linux kernel source tree
7b6f16a258
Marvell/NXP Wi-Fi adapters allow fine-grained adjustment of the transmit
power levels and various other internal parameters. This is done by
sending command streams to the adapter. One storage format of these
command streams are the rgpower tables, which consist of multiple
command blocks in the following format:
command_block_1 = {
XX XX LL LL XX XX ..
}
command_block_n = {
XX XX LL LL XX XX XX ..
}
XX = raw byte as hex chars
LL = total length of the "raw" command block
These command blocks are parsed into their binary representation and
then send to the adapter. The parsing logic was adapted from NXP's
mwifiex driver[1].
The rgpower tables matching the currently set regulatory domain are
automatically requested and applied. If not found the existing device
tree provided power tables are tried as well.

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.
