Bluetooth: hci_bcm: Add support for FW loading in autobaud mode

2022-07-22T00:04:38+00:00

Use the presence of a DT property, "brcm,requires-autobaud-mode", to enable startup in autobaud mode. If the property is present, the device is started in autobaud mode by asserting RTS (BT_UART_CTS_N) prior to powering on the device. Also prevent the use of unsupported commands for devices started in autobaud mode. Only a limited subset of HCI commands are supported in autobaud mode. Some devices (e.g. CYW5557x) require autobaud mode to enable FW loading. Autobaud mode can also be required on some boards where the controller device is using a non-standard baud rate in normal mode when first powered on.

Bluetooth: btbcm: Make btbcm_setup_patchram use btbcm_finalize

2020-04-22T17:43:58+00:00

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 Signed-off-by: Marcel Holtmann

Bluetooth: btbcm: Fold Patch loading + applying into btbcm_initialize()

2020-04-22T17:43:58+00:00

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. Signed-off-by: Hans de Goede Signed-off-by: Marcel Holtmann

Bluetooth: btbcm: Add missing static inline in header

Bluetooth: btbcm: Support pcm configuration

2019-11-27T07:09:55+00:00

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 Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btbcm: Allow using btbcm_initialize() for reinit

2018-05-18T04:37:51+00:00

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

2018-01-10T18:00:14+00:00

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
