Lukas Wunner ff8759609d Bluetooth: btbcm: Fix sleep mode struct ordering
According to the documentation for Laird SD40 radio modules (which use
the BCM4329 chipset), the order of the Enable_BREAK_To_Host and
Pulsed_HOST_WAKE parameters in the sleep mode struct is reversed
vis-à-vis our struct declaration.  See page 46 of this PDF:

http://cdn.lairdtech.com/home/brandworld/files/Application%20Note%20-%2040%20Series%20Bluetooth.pdf

The documentation is dated Oct 2015, so fairly recent, making it appear
more likely that the documentation is correct and our code is wrong.
Amend our code to be in congruence with the documentation.

Frederic Danis 75e167e6f0 Bluetooth: btbcm: Add helper functions for UART setup
Firmware loading may reset the controller UART speed and needs to set
host UART speed back to init speed.

UART drivers setup is split in 3 parts:
- btbcm_initialize() resets the controller and returns the firmware
  name based on controller revision and sub_version.
- btbtcm_patchram() (already existing and public), which takes the
  firmware name as parameter, requests the firmware and loads it to
  the controller.
- btbcm_finalize() which resets the controller, reads local version
  and checks if the controller address is a default one or not.

Remove firmware name retrieval for UART controllers from
btbcm_setup_patchram().

Frederic Danis 18aeb4445a Bluetooth: btbcm: Move request/release_firmware()
Move request/release_firmware() out of btbcm_patchram().
This allows a better error management, if request_firmware() returns an
error then the controller will be used without firmware loading and 0 is
returned.
This will imply to change btbcm_patchram() to accept a firmware instead
of firmware name.

Marcel Holtmann 50862ee557 Bluetooth: btbcm: Export patchram download as separate function
This isolates the Broadcom patchram download procedure as separate
function so that it can be easily used from USB and UART based drivers.

Marcel Holtmann 4fba30f07f Bluetooth: btbcm: Introduce generic Broadcom Bluetooth support
The majority of Broadcom Bluetooth vendor commands are shared between
USB and UART transports. This creates a separate module that eventually
will hold all Broadcom specific commands, but for now just start with
the commands to change the Bluetooth public address and check for the
default address.
