-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";
- };
- };
