Linux kernel source tree

During rmmod, the ath11k host driver sends a QMI MODE OFF command to firmware. As part of this command, firmware initiates WLAN de-initialization and accesses certain UMAC registers during this process. Currently, on WCN6750 WLAN hardware, the system is in a sleep state when firmware receives the QMI MODE OFF command. This results in a firmware/hardware reset while accessing the UMAC hardware registers during sleep state. To avoid this, add logic to send WCN6750 hardware specific WMI_PDEV_SUSPEND_AND_DISABLE_INTR command to firmware prior to sending the QMI MODE OFF command. This will cause firmware to cease all activities and put the device in a powered-on state that prevents access to registers which have been powered off.

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.
