[GIT PULL] tee subsys for v5.1

[GIT PULL] tee subsys for v5.1

[Jens Wiklander]

Hello arm-soc maintainers,

Please pull this TEE subsystem enhancement. A tee bus driver framework
is introduced in order to support an OP-TEE based RNG driver.

The last commit makes changes under drivers/char/hw_random which
also are acked by that maintainer.

This time I've relied on others to review the bus driver framework.
Please take an extra look at it if you can spare the time.

By the way, I've just renewed my PGP subkey so you may need to refresh
it in order to verify the signature.

Thanks,
Jens

[GIT PULL] tee subsys for v5.1

[Jens Wiklander]

Hello arm-soc maintainers,

Please pull these small TEE subsystem updates. The license for two .h
files in OP-TEE driver is clarified with a dual license. The kernel
space tee client interface is complemented with cancellation support.

I've based this pull request on the last pull request I did (now in
the drivers/tee branch) in order to avoid a conflict with "tee: add
cancellation support to client interface".

Thanks,
Jens
