From: Maxim Uvarov
Date: Mon May 25 2020 - 07:52:45 EST


v3: - support tee-suppicant restart (Jens Wiklander)
- description and comments ( Jarkko Sakkinen)
- do not name optee drivers by index in sysfs (Sumit Garg)
v2: - write TEE with capital letters.
- declare __optee_enumerate_device() as static.

Hello,

This patchset fixes issues with probing() tee, optee and optee driver
if they were compiled into kernel, built as modules or any mixed
combination.
These changes require optee-os changes which already were merged.
Main corresponding commits are:
https://github.com/OP-TEE/optee_os/commit/9389d8030ef198c9d7b8ab7ea8e877e0ace3369d
https://github.com/OP-TEE/optee_os/commit/bc5921cdab538c8ae48422f5ffd600f1cbdd95b2

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.

optee: do drivers initialization before and after tee-supplicant run
optee: use uuid for sysfs driver entry
