OP-TEE based fTPM Trusted Application depends on tee-supplicant to provide NV RAM implementation based on RPMB secure storage. So this dependency can be resolved via TEE bus where we only invoke fTPM driver probe once fTPM device is registered on the bus which is only true after the tee-supplicant is up and running. Additionally, TEE bus provides auto device enumeration.
