Linux kernel source tree
c38406aa46
The BAM Data Multiplexer provides access to the network data channels of modems integrated into many older Qualcomm SoCs, including MSM8916. Add the nodes for the BAM DMA engine and BAM-DMUX to enable using WWAN on smartphones/tablets based on MSM8916. This should work out of the box with open-source WWAN userspace such as ModemManager. The nodes are disabled by default to avoid loading unnecessary drivers on devices that cannot use BAM-DMUX (e.g. DragonBoard 410c). However, strictly speaking the nodes could be enabled by default since both the bam_dma and bam_dmux driver will simply do nothing if the modem does not announce any BAM-DMUX channels.

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.
