Not really, but you can take a look at the "Bluetooth: Add support for
Intel Bluetooth device [[8087:07dc]" patch that's currently going
through some feedback rounds on linux-bluetooth. It's one of the first
users of this new API.

Basically what you have is the new setup() callback for HCI drivers and
then a new __hci_cmd_sync() function that can be used from within the
setup() callback to synchronously send whatever HCI commands you need to
send before proceeding with the normal HCI init sequence within the HCI
core.

To my understanding Marcel has planned to move the vendor specific btusb
routines into their own files in the long run (I believe he's used a
term "mini driver" for this) but for now the changes are expected to go
to the main btusb.c file.
