WCN6750 is non-DBS 2x2 11AX chipset. Unlike QCA6390 which is a DBS (dual band simultaneous) solution (2 LMACs), WCN6750 has a single LMAC supporting 2G, 5G and 6G bands but will operate only on one band at any given point. WCN6750 is a PCIe based solution, but it is attached to the WPSS (Wireless Processor SubSystem) Q6 processor, hence it is enumerated by the Q6 processor. It is registered to the APSS processor (Application Processor SubSystem) as a platform device(AHB) and remoteproc APIs are used to boot up or shutdown the device like other AHB devices. Also, Device information like BAR and it's size is not known to the APSS processor as the chip is enumerated by WPSS Q6. These details are fetched over QMI. STA and AP modes are supported. Verified basic connectivity and ping in both the modes. An important point to note is that though WCN6750 is a PCIe device, it cannot be attached to any other platform except on Qualcomm Snapdragon SoCs due to the aforementioned reasons.

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.
