I would take a look at using at least the 3.10 kernel from Atmel. It's the most stable one they have and it's where they've been backporting additional device tree support. I believe if you use my defconfig, you should be able to build a 3.10 kernel with Atmel's latest layer. And definitely start reading up on device tree development. It takes some getting used to but it is a good step forward.
