2024-05-14Bluetooth: qca: clean up definesJohan Hovold
Clean up the QCA driver defines by dropping redundant parentheses around values and making sure they are aligned (using tabs only). Signed-off-by: Johan Hovold <johan+linaro@kernel.org> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
2024-05-03Bluetooth: qca: fix info leak when fetching fw build idJohan Hovold
Add the missing sanity checks and move the 255-byte build-id buffer off the stack to avoid leaking stack data through debugfs in case the build-info reply is malformed.

2024-05-03Bluetooth: qca: generalise device address checkJohan Hovold
The default device address apparently comes from the NVM configuration file and can differ quite a bit between controllers. Store the default address when parsing the configuration file and use it to determine whether the controller has been provisioned with an address. This makes sure that devices without a unique address start as unconfigured unless a valid address has been provided in the devicetree.

2023-10-23Bluetooth: qca: add support for QCA2066Tim Jiang
This patch adds support for QCA2066 firmware patch and NVM downloading. as the RF performance of QCA2066 SOC chip from different foundries may vary. Therefore we use different NVM to configure them based on board ID.

2020-02-28Bluetooth: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

QCA BTSOC NVM is a customized firmware file and different vendors may want to have different BTSOC configuration (e.g. Configure SCO over PCM or I2S, Setting Tx power, etc.) via this file.

2019-07-06Bluetooth: btqca: inject command complete event during fw downloadBalakrishna Godavarthi
Latest qualcomm chips are not sending an command complete event for every firmware packet sent to chip. They only respond with a vendor specific event for the last firmware packet. This optimization will decrease the BT ON time. Due to this we are seeing a timeout error message logs on the console during firmware download. Now we are injecting a command complete event once we receive an vendor specific event for the last RAM firmware packet.

Instead of duplicating the same functions for new chip, update names of the functions that are used for both chips to keep this generic and would help in future when we would have new BT SoC. To have generic text in logs updated from ROME to QCA where ever possible. This avoids confusion to user, when using the future Qualcomm Bluetooth SoC's.

2018-05-18Bluetooth: btqca: Add AR3002 rampatch supportLoic Poulain
This patch adds rampatch download compatibility for ROME >= 3.2. Starting with ROME 3.2, the 'download mode' field of the rampatch header indicates if the controller acknowledges (or not) the received rampatch segments. If not, we need to send all the segments without expecting any event from the controller (except for the last segment). Goal is (I assume) to speed-up rampatch download. This fixes BT on Dragonboard-600c P2 which includes the following BT controller: hci0: ROME Patch Version Request hci0: Product:0x00000008 hci0: Patch :0x00000111 hci0: ROM :0x00000302 hci0: SOC :0x00000023 Signed-off-by: Loic Poulain <loic.poulain@linaro.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
