Chris Mason 7bee8b08c4 Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on Apple
Commit 1c8ba6d013 moved around the setup code for broadcomm chips,
and also added btbcm_read_verbose_config() to read extra information
about the hardware.  It's returning errors on some macbooks:

Bluetooth: hci0: BCM: Read verbose config info failed (-16)

Which makes us error out of the setup function.  Since this
probe isn't critical to operate the chip, this patch just changes
things to carry on when it fails.

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.

Frederic Danis 43b79209b5 Bluetooth: btbcm: Fix calls to __hci_cmd_sync()
Remove test of command reply status as it is already performed by
__hci_cmd_sync().

__hci_cmd_sync_ev() function already returns an error if it got a
non-zero status either through a Command Complete or a Command
Status event.

For both of these events the status is collected up in the event
handlers called by hci_event_packet() and then passed as the second
parameter to req_complete_skb(). The req_complete_skb() callback in
turn is hci_req_sync_complete() for __hci_cmd_sync_ev() which stores
the status in hdev->req_result. The hdev->req_result is then further
converted through bt_to_errno() back in __hci_cmd_sync_ev().

This isolates the Broadcom patchram download procedure as separate
function so that it can be easily used from USB and UART based drivers.

firmare naming prefix. So add a separate table for these devices.

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.
