linux-integrity@vger.kernel.org is the mailing list for TPM and IMA targeted patches and discussion.
- Subscription information is here: http://vger.kernel.org/vger-lists.html#linux-integrity
For non-trivial patch sets, such as patch sets that touch multiple subsystems, it is recommended to CC the linux-security-module@vger.kernel.org mailing list for more broad screening.
TPM and IMA have have their own maintainers and GIT trees:
- IMA: Mimi Zohar, git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity.git
- TPM: Jarkko Sakkinen, git://git.infradead.org/users/jjs/linux-tpmdd.git
TPM 2.0
The TPM 2.0 infrastructure in and around linux is currently moving fast. Here is a link list which tries to capture the current situation.

Intel TSS Stack
The Intel TSS Stack, compliant with the TCG SAPI specifications consists of
- The Stack: https://github.com/01org/tpm2-tss

IBM TSS Stack
The IBM Stack follows a more pragmatic approach - the code can be found at
including tools and everything.
James Bottomley has been actively developing against it

- https://blog.hansenpartnership.com/tpm-enabling-gnome-keyring/
- https://blog.hansenpartnership.com/tpm2-and-linux/
It comes with its own
