Subject: [PATCH v2 0/5] Extend TPM PPI interface to support revision 1.3

This series of patches extends the TPM subsystem's PPI support to
support TPM PPI revision 1.3 where more commands are supported (up to 101)
and the TPM 2 command code '23' takes an additional parameter.

For the command code '23' see this document here on document page 39:
https://trustedcomputinggroup.org/wp-content/uploads/Physical-Presence-Interface_1-30_0-52.pdf

   Stefan

v1->v2:
  - reformatted badly aligned code
  - changed TPM_PPI_REVISION_1 to TPM_PPI_REVISION_ID_1
  - Added R-b's and T-b's

Stefan Berger (5):
  tpm: ppi: pass function revision ID to tpm_eval_dsm()
  tpm: ppi: rename TPM_PPI_REVISION_ID to TPM_PPI_REVISION_ID_1
  tpm: ppi: Display up to 101 operations as define for version 1.3
  tpm: ppi: Possibly show command parameter if TPM PPI 1.3 is used
  tpm: ppi: Enable submission of optional command parameter for PPI 1.3
