+Qualcomm crypto engine driver
+
+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@fd45a000 {
+ compatible = "qcom,crypto-v5.1";
+ reg = <0xfd45a000 0x6000>;
+ clocks = <&gcc GCC_CE2_AHB_CLK>,
+ <&gcc GCC_CE2_AXI_CLK>,
+ <&gcc GCC_CE2_CLK>;
+ clock-names = "iface", "bus", "core";
+ dmas = <&cryptobam 2>, <&cryptobam 3>;
+ dma-names = "rx", "tx";
+ };
