+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";
+ };
+ };
