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

Johan Hedberg says:

====================
pull request: bluetooth-next 2015-05-28

Here's a set of patches intended for 4.2. The majority of the changes
are on the 802.15.4 side of things rather than Bluetooth related:

 - All sorts of cleanups & fixes to ieee802154 and related drivers
 - Rework of tx power support in ieee802154 and its drivers
 - Support for setting ieee802154 tx power through nl802154
 - New IDs for the btusb driver
 - Various cleanups & smaller fixes to btusb
 - New btrtl driver for Realtec devices
 - Fix suspend/resume for Realtek devices

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

* This yields a minimum time of 208 us between the last data of a
