Subject: [GIT PULL] optee bus for v5.9

Hello arm-soc maintainers,

Please pull these patches enabling multi-stage OP-TEE bus enumeration
and also adds a TPM driver for a OP-TEE based fTPM Trusted Application.

The TPM driver depends on and takes advantage of the multi-stage OP-TEE bus
enumeration by indicating that it should be probed after tee-supplicant has
been started.

Jarkko, one of the TPM maintainers, has been involved in reviewing these
patches and agrees that I can include the TPM patch in the pull request.

Thanks,
Jens

  tpm_ftpm_tee: register driver on TEE bus (2020-07-10 09:41:58 +0200)

----------------------------------------------------------------
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.
