Add a device tree binding for the TEE-based remote processor control service implemented as an OP-TEE Trusted Application identified by UUID 80a4c275-0a47-4905-8285-1486a9771a08.
Signed-off-by: Arnaud Pouliquen arnaud.pouliquen@foss.st.com --- v21 updates: - rename compatible to exactly match with the TEE UUID - the remoteproc device driver is no more declared as a child, but use phandle as done for the SCMI. - remove linaro,optee-tz bindings update are now useless. --- .../bindings/remoteproc/remoteproc-tee.yaml | 36 +++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/remoteproc-tee.yaml
