Johan Hovold a2812ff7ea Bluetooth: qca: fix device-address endianness commit `77f45cca8b` upstream. The WCN6855 firmware on the Lenovo ThinkPad X13s expects the Bluetooth device address in big-endian order when setting it using the EDL_WRITE_BD_ADDR_OPCODE command. Presumably, this is the case for all non-ROME devices which all use the EDL_WRITE_BD_ADDR_OPCODE command for this (unlike the ROME devices which use a different command and expect the address in little-endian order). Reverse the little-endian address before setting it to make sure that the address can be configured using tools like btmgmt or using the 'local-bd-address' devicetree property. Note that this can potentially break systems with boot firmware which has started relying on the broken behaviour and is incorrectly passing the address via devicetree in big-endian order. The only device affected by this should be the WCN3991 used in some Chromebooks. As ChromeOS updates the kernel and devicetree in lockstep, the new 'qcom,local-bd-address-broken' property can be used to determine if the firmware is buggy so that the underlying driver bug can be fixed without breaking backwards compatibility. Set the HCI_QUIRK_BDADDR_PROPERTY_BROKEN quirk for such platforms so that the address is reversed when parsing the address property.

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.
