Merge tag 'optee-bus-for-v5.9' of git://git.linaro.org/people/jens.wiklander/linux-tee into arm/drivers
Enable multi-stage OP-TEE bus enumeration
Probes drivers on the OP-TEE bus in two steps. First for drivers which
do not depend on tee-supplicant. After tee-supplicant has been started
probe the devices which do depend on tee-supplicant.
Also introduces driver which uses an OP-TEE based fTPM Trusted
Application depends on tee-supplicant NV RAM implementation based on
RPMB secure storage.
* tag 'optee-bus-for-v5.9' of git://git.linaro.org/people/jens.wiklander/linux-tee:
tpm_ftpm_tee: register driver on TEE bus
optee: enable support for multi-stage bus enumeration
optee: use uuid for sysfs driver entry
