2017-02-16Bluetooth: btbcm: Add a delay for module resetWen-chien Jesse Sung1-0/+3
Some btbcm devices require more time to complete its reset process. They won't reply any hci command until reset is done. [ 17.218554] Bluetooth: hci0 command 0x1001 tx timeout [ 25.214999] Bluetooth: hci0: BCM: Reading local version info failed (-110) Signed-off-by: Wen-chien Jesse Sung <jesse.sung@canonical.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2016-02-23Bluetooth: btbcm: Fix handling of firmware not foundPetri Gynther1-1/+2
If the call to request_firmware() fails in btbcm_setup_patchram(), the BCM chip will be operating with its default firmware. In this case, btbcm_setup_patchram() should not return immediately but instead should skip to btbcm_check_bdaddr() and quirk setup.

2015-10-21Bluetooth: btbcm: Read USB product information for Apple devicesMarcel Holtmann1-0/+9
For the Apple Bluetooth devices, read the USB product information and print them. This allows for easy mapping of chip and USB details. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-10-21Bluetooth: btbcm: Fix firmware version number calculationMarcel Holtmann1-4/+4
The calculation for the firmware version number is off by one bit. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-10-07Bluetooth: btbcm: Read the local name in setup stageMarcel Holtmann1-0/+44
The Broadcom Bluetooth controllers have the chip name included in the ROM firmware or later in the patchram firmware. For debugging purposes read the local name and print it out. This is only done during setup stage and only once before loading the firmware and once after loading the firmware. For the Broadcom based controllers from Apple, the name is only read once after determining the chip id.

2015-10-05Bluetooth: btbcm: Send HCI Reset before sending Apple specific commandsMarcel Holtmann1-2/+8
The commit 7bee8b08c428 allows the Read Verbose Config Info to fail gracefully and not cause the controller setup to abort. It seems the reason that command failed in the first place was the missing HCI Reset to bring the controller in full Bluetooth mode. Apple Bluetooth controllers start out in HID mode and when in that mode the Read Verbose Config Info command is not allowed. Sending HCI Reset switches the controller into full HCI mode.

2015-07-14Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on AppleChris Mason1-6/+5
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.

2015-06-06Bluetooth: btbcm: Add helper functions for UART setupFrederic Danis1-0/+89
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(). Signed-off-by: Frederic Danis <frederic.danis@linux.intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2015-06-06Bluetooth: btbcm: Move request/release_firmware()Frederic Danis1-14/+12
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.

2015-05-15Bluetooth: btbcm: Fix calls to __hci_cmd_sync()Frederic Danis1-6/+0
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().

2015-04-30Bluetooth: btbcm: Export patchram download as separate functionMarcel Holtmann1-69/+79
This isolates the Broadcom patchram download procedure as separate function so that it can be easily used from USB and UART based drivers. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-04-07Bluetooth: btbcm: Add firmware table for UART based devicesMarcel Holtmann1-15/+41

2015-04-07Bluetooth: btbcm: Add support for Broadcom controller setupMarcel Holtmann1-0/+258

2015-04-07Bluetooth: btbcm: Introduce generic Broadcom Bluetooth supportMarcel Holtmann1-0/+99
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.
