2020-04-22Bluetooth: btbcm: Make btbcm_setup_patchram use btbcm_finalizeHans de Goede
On UART attached devices we do: 1. btbcm_initialize() 2. Setup UART baudrate, etc. 3. btbcm_finalize() After our previous changes we can now also use btbcm_finalize() from the btbcm_setup_patchram() function used on USB devices without any functional changes. This completes unifying the USB and UART paths as much as possible. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2020-04-22Bluetooth: btbcm: Fold Patch loading + applying into btbcm_initialize()Hans de Goede
Instead of having btbcm_initialize() fill a passed in fw_name buffer and then have its callers use that to request the firmware + load it into the HCI, make btbcm_initialize() do this itself the first time it is called (its get called a second time to reset the HCI after the firmware has been loaded). This removes some code duplication and makes it easier for further patches in this series to try more then 1 firmware filename.

2019-11-27Bluetooth: btbcm: Support pcm configurationAbhishek Pandit-Subedi
Add BCM vendor specific command to configure PCM parameters. The new vendor opcode allows us to set the sco routing, the pcm interface rate, and a few other pcm specific options (frame sync, sync mode, and clock mode). See broadcom-bluetooth.txt in Documentation for more information about valid values for those settings. Here is an example trace where this opcode was used to configure a BCM4354: < HCI Command: Vendor (0x3f|0x001c) plen 5 01 02 00 01 01 > HCI Event: Command Complete (0x0e) plen 4 Vendor (0x3f|0x001c) ncmd 1 Status: Success (0x00) We can read back the values as well with ocf 0x001d to confirm the values that were set: $ hcitool cmd 0x3f 0x001d < HCI Command: ogf 0x3f, ocf 0x001d, plen 0 > HCI Event: 0x0e plen 9 01 1D FC 00 01 02 00 01 01 Signed-off-by: Abhishek Pandit-Subedi <abhishekpandit@chromium.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2018-05-18Bluetooth: btbcm: Allow using btbcm_initialize() for reinitHans de Goede
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".

2018-01-10Bluetooth: btbcm: Fix sleep mode struct orderingLukas Wunner
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.

2015-06-06Bluetooth: btbcm: Add helper functions for UART setupFrederic Danis
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 Danis
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.

The majority of Broadcom Bluetooth vendor commands are shared between USB and UART transports.
