OP-TEE Device Tree Bindings
OP-TEE is a piece of software using hardware features to provide a Trusted
Execution Environment. The security can be provided with ARM TrustZone, but
also by virtualization or a separate chip.
We're using "linaro" as the first part of the compatible property for
the reference implementation maintained by Linaro.
* OP-TEE based on ARM TrustZone required properties:
- compatible : should contain "linaro,optee-tz"
- method : The method of calling the OP-TEE Trusted OS. Permitted
values are:
"smc" : SMC #0, with the register assignments specified
in drivers/tee/optee/optee_smc.h
"hvc" : HVC #0, with the register assignments specified
in drivers/tee/optee/optee_smc.h
Example:
firmware {
optee {
compatible = "linaro,optee-tz";
method = "smc";
};
};
