Marek Vasut b6b56ea020 Bluetooth: hci_bcm: Add CYW4373A0 support 
[ Upstream commit 02d056a340 ]

CYW4373A0 is a Wi-Fi + Bluetooth combo device from Cypress.
This chip is present e.g. on muRata 2AE module.

This chip has additional quirk where the HCI command 0xfc45, used on
older chips to switch UART clock from 24 MHz to 48 MHz, to support
baudrates over 3 Mbdps, is no longer recognized by this newer chip.
This newer chip can configure the 4 Mbdps baudrate without the need
to issue HCI command 0xfc45, so add flag to indicate this and do not
issue the command on this chip to avoid failure to set 4 Mbdps baud
rate.

It is not clear whether there is a way to determine which chip does
and which chip does not support the HCI command 0xfc45, other than
trial and error.

README 

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.
