[PATCH v2 3/3] Bluetooth: hci_ll: Add optional nvmem BD address source

This adds an optional nvmem consumer to get a BD address from an external source. The BD address is then set in the Bluetooth chip after the firmware has been loaded. This has been tested working with a TI CC2560A chip (in a LEGO MINDSTORMS EV3). Signed-off-by: David Lechner

[PATCH v2 1/3] Bluetooth: hci_ll: add support for setting public address

This adds support for setting the public address on Texas Instruments Bluetooth chips using a vendor-specific command. This has been tested on a CC2560A. The TI wiki also indicates that this command should work on TI WL17xx/WL18xx Bluetooth chips. Signed-off-by: David Lechner
