Martin Blumenstingl c50903e3ee Bluetooth: btrtl: add support for the RTL8723BS and RTL8723DS chips
The Realtek RTL8723BS and RTL8723DS chipsets are SDIO wifi chips. They
also contain a Bluetooth module which is connected via UART to the host.

Realtek's userspace initialization tool (rtk_hciattach) differentiates
these two via the HCI version and revision returned by the
HCI_OP_READ_LOCAL_VERSION command.
Additionally we apply these checks only the for UART devices. Everything
else is assumed to be a "RTL8723B" which was originally supported by the
driver (communicating via USB).

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
