The flow of 11d scan is: 1. trigger 11d scan. 2. receive, parse, and update 11d scan result. 3. stop 11d scan. So need to add handler for WMI_11D_SCAN_START_CMDID and WMI_11D_SCAN_STOP_CMDID to trigger/stop 11d scan. Add process of WMI event WMI_11D_NEW_COUNTRY_EVENTID for 11d scan result. There are two points that need to be noted: 1. The 11d scan priority is 'MEDIUM' in firmware, the hw scan priority is 'LOW'. When 11d scan is running, hw scan will be canceled. To avoid this, change the hw scan priority to 'MEDIUM' when 11d scan is running. 2. Need to add wait_for_completion_timeout() for scan.complete in ath12k_reg_update_chan_list() because 11d scan will cost more than 5 seconds. Due to another existing wait in ath12k_scan_stop(), there will be two scan.complete in different threads. Therefore use complete_all() instead of complete() for scan.complete. complete_all() can work well when it is only one thread wait for scan.complete.

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.
