This patch set fixes and unifies the behaviour. v2: The drivers tpm_nsc and tpm_infineon were forgotten. For this version I checked both with find and command and from Kconfig that everything that is supposed to be a driver directly interfacing with the TPM core, is included (e.g. discluding tpm_tis_spi).
