Linux kernel source tree
9148ac0a16
This adds support for setting BD address during hci registration. NXP FW does not allow vendor commands unless it receives a reset command after FW download and initialization done. As a workaround, the .set_bdaddr callback function will first send the HCI reset command, followed by the actual vendor command to set BD address. The driver checks for the local-bd-address property in device tree, and if preset, it sets the HCI_QUIRK_USE_BDADDR_PROPERTY quirk. With this quirk set, the driver's set_bdaddr callback function is called after FW download is complete and before HCI initialization, which sends the hci reset and 3f 22 commands. During initialization, kernel reads the newly set BD address from the controller.

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.
