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";

	};
