This constitutes as a strong need for that, but you need just that, no need to have any notion or info to indicate TrEE/TEE as you know this product runs those in TEE. In short, just use the platform specific(not SoC or SoC family) specific compatible to initialise your driver and don't introduce any specific compatible for this particular firmware interface need. -- Regards, Sudeep
