-Required properties:
-
-- compatible  : should be "qcom,crypto-v5.1"
-- reg         : specifies base physical address and size of the registers map
-- clocks      : phandle to clock-controller plus clock-specifier pair
-- clock-names : "iface" clocks register interface
-                "bus" clocks data transfer interface
-                "core" clocks rest of the crypto block
-- dmas        : DMA specifiers for tx and rx dma channels. For more see
-                Documentation/devicetree/bindings/dma/dma.txt
-- dma-names   : DMA request names should be "rx" and "tx"

-Example:
-	crypto@...5a000 {
