tpm: Make chip->{status,cancel,req_canceled} opt (2025-03-27 17:10:43 +0200)
----------------------------------------------------------------
Hi,
This PR contains a new driver: TPM FF-A driver. FF comes from Firmware
Framework, and A comes from Arm's A-profile [1]. FF-A is essentially
a standard mechanism to communicate with TrustZone apps such as TPM.
Other than that, the PR includes a pile of fixes and small improvments.
BR, Jarkko
