What we do know for sure about the Three-Eyed Raven is that he is a Greenseer, gifted with the ability to see the past, present, and future and communicate through dreams. Greensight is more common with the Children of the Forest, but some humans, like the Three-Eyed Raven, also have this ability.
There are a lot of theories surrounding the identity of the Three-Eyed Raven, and the character's final words to Bran (It's time for you to become me) have only fueled some of these. It has been suggested that Bran will go back in time and train up the Raven, who will in turn train up Bran in a continual time-loop.
