Introduce compatible "linaro,scmi-optee" for SCMI transport channel based on an OP-TEE service invocation. Define "linaro,optee-channel-id" property to identify the OP-TEE SCMI channel used by the protocol(s). OP-TEE SCMI transport can either use shared memory or a static shared memory buffer identified by the DT. These bindings were posted to the Linux kernel DT bindings mailing list and acked by maintainer [1].

Device Tree Bindings Staging Area ================================= This directory contains device tree bindings for U-Boot. These follow along with Linux kernel bindings, with a few additions. By adding the files here, U-Boot patches can clearly show thees additions. This makes it easier for device tree people to review these additions in patches sent to the U-Boot mailing list. The intent IS to commit these files to U-Boot. Hopefully at some point the files will be stored in another repo (shared with Linux) which is brought in as needed. Changes here are intended to mirror changes in the Linux Documentation/devicetree/bindings/ directory. sjg@chromium.org 17-Jan-12
