I recently hacked the Hifiberry-DAC driver so that it would support the PT8211 16 bit stereo DAC. This works flawlessly, and it's damn easy to wire this up to the pi. I'd like to make this a real driver and contribute to rpi-linux repository. Unfortunately, when I change the name from snd-soc-hifiberry-dac.ko to snd-soc-pt8211.ko, it just refuses to work. Is this a driver tree issue? Can anybody help me? I'd like to contribute, especially since the PT8211 is so easy to work with and nice for beginners...
