I found something truly weird based on your dmesg outputs:
% git --no-pager grep IFX0102 drivers/char/tpm
drivers/char/tpm/tpm_infineon.c: {"IFX0102", 0},
drivers/char/tpm/tpm_tis.c: {"IFX0102", 0}, /* Infineon */
I.e.
tpm_tis: 1.2 TPM (device-id 0xB, rev-id 16)
tpm tpm0: tpm_try_transmit: send(): error -5
tpm tpm0: A TPM error (-5) occurred attempting to determine the timeouts
tpm_tis tpm_tis: Could not get TPM timeouts and durations
tpm_tis 00:08: 1.2 TPM (device-id 0xB, rev-id 16)
tpm tpm0: tpm_try_transmit: send(): error -5
tpm tpm0: A TPM error (-5) occurred attempting to determine the timeouts
tpm_tis 00:08: Could not get TPM timeouts and durations
ima: No TPM chip found, activating TPM-bypass!
tpm_inf_pnp 00:08: Found TPM with ID IFX0102
The HID is associated with two drivers and the last log entry tells that
tpm_inf_pnp was successfully initialized.
Given that tpm_tis showed problems already in the in v4.15, it would
clue that tpm_tis driver should not include IFX0102.

[PATCH] tpm: add HID module parameter
I recently found that not all BIOS manufacturers are using the specified
generic PNP id in their TPM ACPI table entry. I have added the vendor
specific IDs that I know about and added a module parameter that a user can
specify another HID to the probe list if their device isn't being found by
the
default list.

and
% git --no-pager grep ATM1200 drivers/char/tpm
drivers/char/tpm/tpm_tis.c: {"ATM1200", 0}, /* Atmel */
% git --no-pager grep BCM0101 drivers/char/tpm
drivers/char/tpm/tpm_tis.c: {"BCM0101", 0}, /* Broadcom */
% git --no-pager grep NSC1200 drivers/char/tpm
drivers/char/tpm/tpm_tis.c: {"NSC1200", 0}, /* National */
It looks like that that the author was not aware that tpm_infineon.c
already was implemented for IFX0102. The errors come from non-TCG
compatible TPM implemenation tried to be used with the TCG TIS driver.
I'm not sure (yet) if this a full resolution of this bug but it is
obviously something that should be first fixed before making any fast
conclusions on further actions.
If the issue still persists after fixing this, then it is easier to
debug because the bug scoped down to the tpm_infineon driver.
