+ "marvell,kirkwood-crypto"
+ "marvell,dove-crypto"

+- interrupts: interrupt number
+- clocks: reference to the crypto engines clocks. This property is not

+- clock-names: "cesaX" and "cesazX", X should be replaced by the crypto engine
+ id.
+ This property is not required for the orion and kirkwoord

+ "cesazX" clocks are not required on armada-370 platforms
