Linux kernel source tree
5d69351820
The TRF7970a device is sensitive to RF disturbances, which can make it hard to pass some EMC immunity tests. By reducing the RX antenna gain, the device becomes less sensitive to EMC disturbances, as a trade-off against antenna performance. Add a device tree option to select RX gain reduction to improve EMC performance. Selecting a communication standard in the ISO control register resets the RX antenna gain settings. Therefore set the RX gain reduction everytime the ISO control register changes, when the option is used.

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.
