TPM2 is still pretty new. I don't know that you'll ever see docs
specific to the PTT TPM2 implementation but support for the baseline
TPM2 commands went into the Linux kernel in the 3.20 security subsystem
patch set. Some useful links:

I don't know the status of current TPM2 driers off the top of my head
but Jarkko Sakkinen is keeping his linux-tpm2 branch on github:
https://github.com/jsakkine/linux-tpm2. He has a branch that looks relevant.
If you do manage to get a TPM2 driver loaded there aren't any userspace
tools yet AFAIK. Still, just getting the driver loaded would be
interesting and I'd be interested to hear about your progress.
