Hi James,
Sorry for a late PR.
Summary of the content:
* Reduced polling delays in tpm_tis.
* Support for retrieving TPM 2.0 Event Log through EFI before
ExitBootServices.
* Replaced tpm-rng.c with a hwrng device managed by the driver for each
TPM device.
* TPM resource manager synthesizes TPM_RC_COMMAND_CODE response instead
of returning -EINVAL for unknown TPM commands. This makes user space
more sound.
* CLKRUN fixes:
* Keep #CLKRUN disable through the entier TPM command/response flow.
* Check whether #CLKRUN is enabled before disabling and enabling it
again because enabling it breaks PS/2 devices on a system where it
is disabled.
