+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. As there's no single OP-TEE
+vendor we're using "optee" as the first part of compatible property,
+indicating the OP-TEE protocol is used when communicating with the secure
+world.
+
+* OP-TEE based on ARM TrustZone required properties:
+
+- compatible="optee,optee-tz"
+
+Example:
+ optee {
+ compatible="optee,optee-tz";
+ };
