Subject: [PATCHv2 0/2] optee: register drivers on optee bus

v2: - write TEE with capital letters.
    - declare __optee_enumerate_device() as static.


This patchset fixes issues with probing() tee, optee and optee driver
if they were compiled into kernel, built as modules or any mixed
These changes require optee-os changes which already were merged.
Main corresponding commits are:

optee_enumerate_devices() which discovers Trusted Applications on tee
bus is split up on 2 changes. Do probe of drivers which do not require
userspace support of tee-supplicant and stage two to run drivers with
support of tee-supplicant only after tee supplicant run. 

Best regards,

Maxim Uvarov (2):
  optee: do drivers initialization before and after tee-supplicant run
  tpm_ftpm_tee: register driver on TEE bus
