Optee device names for sysfs needed to be unique

and it's better if they will mean something. UUID for name looks like good solution: /sys/bus/tee/devices/optee-clnt-<uuid>
How about mentioning it is the UUID of the Trusted Application on the TEE side?
Jerome, do you think optee-ta-<uuid> is more suitable here?
Yes, a bit better I think. More "self explanatory"... kind of :)

Is it possible to have several devices bound to the same TA? I think nothing forbids this although we may not have any use case for now...
A single TA is represented via a single device represented via UUID on the TEE bus. And I can't think of a scenario where the user may not want to split the TA so as to support a particular driver in Linux.
