Multiple vendors have supported the AOSP Bluetooth Quality Report. When a Bluetooth controller supports the capability, it can enable the aosp capability through hci_set_aosp_capable. Then hci_core will set up the hdev->aosp_set_quality_report callback through aosp_do_open if the controller responds to support the quality report capability. Note that Intel also supports a distinct telemetry quality report specification. Intel sets up the hdev->set_quality_report callback in the btusb driver module. Reviewed-by: Miao-chen Chou Signed-off-by: Joseph Hwang --- Changes in v6: - Use the decimal version instead of hexadecimal version to be consistent with the AOSP specification. - Move the code of checking the bluetooth_quality_report_support field to the previous patch. Changes in v5: - Fix the patch per [RFC PATCH] Bluetooth: Add framework for AOSP quality report setting - Declare aosp_set_quality_report. - Use aosp_do_open() to set hdev->aosp_set_quality_report. - Add aosp_has_quality_report(). - In mgmt, use hdev->aosp_set_quality_report and hdev->set_quality_report separately. Changes in v4: - Move the AOSP BQR support from the driver level to net/bluetooth/aosp. - Fix the drivers to use hci_set_aosp_capable to enable aosp. - Add Mediatek to support the capability too. Changes in v3: - Fix the auto build test ERROR "undefined symbol: btandroid_set_quality_report" that occurred with some kernel configs. - Note that the mgmt-tester "Read Exp Feature - Success" failed. But on my test device, the same test passed. Please kindly let me know what may be going wrong. These patches do not actually modify read/set experimental features. - As to CheckPatch failed. No need to modify the MAINTAINERS file. Thanks.
