Subject[PATCH v9 0/5] tpm: Command duration logging and chip-specific override
Date
v9: Include command duration in existing error messages rather than
logging an extra debug message. Rebase onto Jarkko's tree.

v8: Fix v7 goof-up in tpm_getcap().

v7: Use tpm_getcap() instead of a redundant new function.

v6: Split tpm_get_cap_prop() out of tpm_get_timeouts(); always return
error on TPM command failure.

v5: Use msecs_to_jiffies() instead of * HZ / 1000.

v4: Rework tpm_get_timeouts() to allow overriding both timeouts and
durations via a single callback.

This series
- improves TPM command error reporting
- adds optional logging of TPM command durations
- allows chip-specific override of command durations as well as protocol
timeouts
- overrides ST19NP18 TPM command duration to avoid lockups

Ed Swierk (5):
tpm_tis: Improve reporting of IO errors
tpm: Add optional logging of TPM command durations
tpm: Clean up reading of timeout and duration capabilities
tpm: Allow TPM chip drivers to override reported command durations
tpm_tis: Increase ST19NP18 TPM command duration to avoid chip lockup
