Merge tag 'tpmdd-next-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd

Pull TPM updates from Jarkko Sakkinen:
 "These are the changes for the TPM driver with a single major new
  feature: TPM bus encryption and integrity protection. The key pair on
  TPM side is generated from so called null random seed per power on of
  the machine [1]. This supports the TPM encryption of the hard drive by
  adding layer of protection against bus interposer attacks.

  Other than that, a few minor fixes and documentation for tpm_tis to
  clarify basics of TPM localities for future patch review discussions
  (will be extended and refined over times, just a seed)"
