Known issues so far: - le32/le64_to_cpu()'s and one cpu_to_le32 missing from tpm_crb.c assuming that CRB driver would be used in big-endian architecture. - I still have troubles having FIFO testing environment so it would not be a big surprise if it had broke for some reason (help with testing and/or bug fixes for FIFO would be highly appreciated). Notes about the implementation: - Reworked the code base to the direction that Jason Gunthorpe suggested. - Moved to use devres in tpm_crb as Jason suggested. - Did some groundwork for implementing Stefan Bergers suggestions to tpm_crb. I hope that it is now more in right direction than in my preview. I'll push fixes on top of tpm2-v1 branch [1] and do not rebase it anymore and therefore it is a good testing branch. When things look good enough I'll create tpm2-v2 branch and prepare and send a new patch set.
