For the Marvell HCI UART we have to upload two firmware files. The first one is only for switching the baudrate of the device to a higher baudrate. After the baudrate switching firmware has been uploaded the device waits for a final ack (0x5a) before actually switching the baudrate. To send this final ack with the old baudrate give the hci ldisc workqueue a chance to run before switching the baudrate. Without this the final ack will never be received by the device and firmware upload fails. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
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.
