With Linux running in Trustzone non-secure world, OP-TEE OS runs in secure world, linux could use secure services provided by OP-TEE. With TEE/OP-TEE options selected, use the bindings in Documentation/devicetree/bindings/arm/firmware/linaro,optee-tz.txt to let the driver probe work. On i.MX6/7, now the bootflow is U-Boot->OP-TEE->Linux, OP-TEE will automatically create that node. Signed-off-by: Peng Fan --- V1: Tested on i.MX7D-SDB with/without OP-TEE OS.
