Subject: [GIT PULL] tpmdd updates for v5.12-rc1

Hi,

This contains bug fixes for tpm_tis driver, which had a racy wait for
hardware state change to be ready to send a command to the TPM chip. The
bug has existed already since 2006, but has only made itself known in
recent past.

There's also couple of new features:

1. Cr50 I2C driver.
2. Sysfs exports of PCR registers in TPM 2.0 chips.
