[ Upstream commit0a491167fe] Most of the txpower for the ath10k firmware is stored as twicepower (0.5 dB steps). This isn't the case for max_antenna_gain - which is still expected by the firmware as dB. The firmware is converting it from dB to the internal (twicepower) representation when it calculates the limits of a channel. This can be seen in tpc_stats when configuring "12" as max_antenna_gain. Instead of the expected 12 (6 dB), the tpc_stats shows 24 (12 dB). Tested on QCA9888 and IPQ4019 with firmware 10.4-3.5.3-00057.

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.
