Bluetooth: btqca: Add support for firmware image with mbn type for WCN6750

2021-06-26T05:12:29Z

1. Added support to download firmware image with mbn type for wcn6750 as it supports mbn type image. 2. If mbn type image is not present then check for tlv type image. 3. Added debug logs for mbn type image. Signed-off-by: Venkata Lakshmi Narayana Gubba Signed-off-by: Marcel Holtmann

Bluetooth: hci_qca: Add support for QTI Bluetooth chip wcn6750

2021-06-26T05:12:29Z

Added regulators,GPIOs and changes required to power on/off wcn6750. Added support for firmware download for wcn6750. Changes done in detail: 1. Added regulators and corresponding current values. 2. Added sw_ctrl GPIO pin which is output from BT SoC and indicates status of clock supply to BT SoC. 3. Added inline function to check if the SoC type is wcn6750. 4. Modified the function qca_wcn3990_init() to support wcn6750 and renamed it to qca_regulator_init(). Signed-off-by: Venkata Lakshmi Narayana Gubba Signed-off-by: Marcel Holtmann

Bluetooth: btqca: Use NVM files based on SoC ID for WCN3991

2020-12-07T14:59:55Z

This change will allow to use different NVM file based on WCN3991 BT SoC ID.Need to use different NVM file based on fab location for WCN3991 BT SoC. Signed-off-by: Venkata Lakshmi Narayana Gubba Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: hci_qca: Disable SoC debug logging for WCN3991

2020-06-12T13:17:47Z

By default, WCN3991 sent debug packets to HOST via ACL packet with header 0xDC2E. This logging is not required on commercial devices. With this patch SoC logging is disabled post fw download. Signed-off-by: Balakrishna Godavarthi Signed-off-by: Marcel Holtmann

Bluetooth: hci_qca: Add support for Qualcomm Bluetooth SoC QCA6390

2020-04-02T06:25:19Z

This patch adds support for QCA6390, including the devicetree and acpi compatible hwid matching, and patch/nvm downloading. Signed-off-by: Rocky Liao Signed-off-by: Marcel Holtmann

Bluetooth: Replace zero-length array with flexible-array member

2020-02-28T07:30:02Z

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.
