- SCO routing to host interface support for the btmrvl driver
- AMP code cleanups
- Fixes to AMP HCI init sequence
- Refactoring of the HCI callback mechanism
- Added shutdown routine for Intel controllers in the btusb driver
- New config option to enable/disable Bluetooth debugfs information
- Fix for early data reception on L2CAP fixed channels
Please let me know if there are any issues pulling. Thanks.
