In patch "Add LoRaWAN API declaration for LoRa devices" you add headers for "API" and here you implement functions. That is just weird. Does it mean you can have other implementations? Also, you don't really have any user of this API in the set. Please introduce at least 1 driver, preferably more (I see that Andreas has multiple ones in his patchset). You cannot push kernel infrastructure without kernel user.
