Linux device tree binding, whose usage is obligatory, comprises faulty representation of Marvell cryptographic engine (CESA) - two engines are artificially gathered into single DT node, in order to avoid certain SW limitation. This patch improves the cesa driver to support above binding, depending on compatible string, which helps to ensure backward compatibility.
