Unlike other ATH11K PCIe devices which are enumerated by APSS processor (Application Processor SubSystem), WCN6750 gets enumerated by the WPSS Q6 processor (Wireless Processor SubSystem); In simple terms, though WCN6750 is PCIe device, it is not attached to the APSS processor, APSS will not know of such a device being present in the system and therefore WCN6750 will be registered as a platform device to the kernel core like other supported AHB devices. WCN6750 needs both AHB and PCI APIs for it's operation, it uses AHB APIs for device probe/boot and PCI APIs for device setup and register accesses. Because of this nature, it is referred as a hybrid bus device. Refactor PCI code to support hybrid bus devices like WCN6750.

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.
