I've played a bit with dt checker and saw that description/type/etc.. are not needed when the property name does not include a coma ','. I think i'll use "optee-channel-id" instead of "linaro,optee-channel-id" as property name. With that name, 'make dt_binding_check' passes without complains on arm,scmi.yaml. I have no strong preference and here and can go either ways. I though the "linaro," was expected. Please tell me if there's any reason I need to preserve this "linaro," prefix on that property.
