I'm running Fedora Workstation with custom compiled kernel 5.5.10-200.fc31.x86_64 with all TPM related configuration enabled. System boots up fine with or without Secure Boot enabled.But, TPM drivers fail to inititalize TPM and create /dev/tpm0.

Windows 10 64bit reports TPM as being initialized and ready. I am able to clear TPM from within Windows and I get the prompt by UEFI to confirm clearing of TPM. UEFI itself doesn't even mention TPM though. Here is what is reported by Windows Tpm-Get Powershell cmdlet.

TpmPresent                : True
TpmReady                  : True
ManufacturerId            : 1229870147
ManufacturerIdTxt         : INTC
ManufacturerVersion       : 10.0.38.1000
ManufacturerVersionFull20 : 10.0.38.1000
ManagedAuthLevel          : Full
OwnerAuth                 : <Owner's Password>
OwnerClearDisabled        : False
AutoProvisioning          : Enabled
LockedOut                 : False
LockoutHealTime           : 2 hours
LockoutCount              : 6
LockoutMax                : 32
SelfTest                  : {}


ACPI DSDT file has an entry for TPM. 

Here's the output from "journalctl | grep -i tpm":

I'd be happy to provide complete logs and any other info needed.

Thanks
