The Devicetree bindings document does not have to say in the title that
it is a "Devicetree binding", but instead just describe the hardware.
Drop trailing "Devicetree bindings" in various forms (also with
trailing full stop):

OP-TEE is a piece of software using hardware features to provide a Trusted
|
|
Execution Environment. The security can be provided with ARM TrustZone, but
|
|
also by virtualization or a separate chip.
|
|
|
|
We're using "linaro" as the first part of the compatible property for
|
|
the reference implementation maintained by Linaro.
