Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next

Johan Hedberg says:

====================
pull request: bluetooth-next 2020-01-26

Here's (probably) the last bluetooth-next pull request for the 5.6 kernel.

 - Initial pieces of Bluetooth 5.2 Isochronous Channels support
 - mgmt: Various cleanups and a new Set Blocked Keys command
 - btusb: Added support for 04ca:3021 QCA_ROME device
 - hci_qca: Multiple fixes & cleanups
 - hci_bcm: Fixes & improved device tree support
 - Fixed attempts to create duplicate debugfs entries

Please let me know if there are any issues pulling. Thanks.
====================
