Bluetooth: btbcm: Allow using btbcm_initialize() for reinit

2018-05-18T04:37:51Z

btbcm_finalize() does a re-init of the controller, which is almost the same as the initial init. Modify btbcm_initialize() so that it can be used for this re-init and modify btbcm_finalize() to use it. As an added bonus this also makes the dev_info from btbcm_finalize() use the proper hw_name instead of always printing "BCM". Signed-off-by: Hans de Goede Signed-off-by: Marcel Holtmann

Bluetooth: btbcm: Fix sleep mode struct ordering

2018-01-10T18:00:14Z

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. Cc: Sue White Reviewed-by: Andy Shevchenko Signed-off-by: Lukas Wunner Signed-off-by: Marcel Holtmann

Bluetooth: btbcm: Support the BCM4354 Bluetooth UART device

Add vendor specific command to change controller device speed. Signed-off-by: Frederic Danis Signed-off-by: Marcel Holtmann

Bluetooth: btbcm: Add helper functions for UART setup

2015-06-06T05:33:25Z

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 Signed-off-by: Marcel Holtmann

Bluetooth: btbcm: Move request/release_firmware()

2015-06-06T05:29:56Z

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. Signed-off-by: Frederic Danis Signed-off-by: Marcel Holtmann

Bluetooth: btbcm: Export patchram download as separate function

2015-04-29T23:05:29Z

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 Signed-off-by: Johan Hedberg

Bluetooth: btbcm: Add support for Broadcom controller setup

2015-04-07T16:47:11Z

To unify the controller setup of Broadcom devices between USB and UART transport, add the patchram download support into the Broadcom module. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btbcm: Introduce generic Broadcom Bluetooth support

2015-04-07T16:47:11Z

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.
