Merge tag 'tpmdd-next-v5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd

Pull tpm updates from Jarkko Sakkinen:

 - Tightened validation of key hashes for SYSTEM_BLACKLIST_HASH_LIST. An
   invalid hash format causes a compilation error. Previously, they got
   included to the kernel binary but were silently ignored at run-time.

 - Allow root user to append new hashes to the blacklist keyring.

 - Trusted keys backed with Cryptographic Acceleration and Assurance
   Module (CAAM), which part of some of the new NXP's SoC's. Now there
   is total three hardware backends for trusted keys: TPM, ARM TEE and
   CAAM.

 - A scattered set of fixes and small improvements for the TPM driver.
