The drivers/bluetooth/controller path adds a native BLE Link Layer (controller and HCI) to the Bluetooth subsystem. This first implementation adds support for the nRF5x series of devices from Nordic Semiconductor. The hal/ folder inside the controller contains all IC-specific code to interface with the radio and baseband.
