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:

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
