Stephan Gerhold says: ==================== net: wwan: Add Qualcomm BAM-DMUX WWAN network driver The BAM Data Multiplexer provides access to the network data channels of modems integrated into many older Qualcomm SoCs, e.g. Qualcomm MSM8916 or MSM8974. This series adds a driver that allows using it. All the changes in this patch series are based on a quite complicated driver from Qualcomm [1]. The driver has been used in postmarketOS [2] on various smartphones/tablets based on Qualcomm MSM8916 and MSM8974 for more than a year now with no reported problems. It works out of the box with open-source WWAN userspace such as ModemManager.

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.
