Subject: [PATCH 08/12] dt-bindings: remoteproc: qcom,smd-edge: define re-usable schema for smd-edge
'smd-edge' property appears in multiple bindings, so split it into one
place which can be re-used. This reduces code duplication and strict
schema matching for smd-edge nodes (instead of just "type:object").
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
