+Required properties:
+- compatible: should be "rockchip,crypto"
+- reg: base physical address of the engine and length of memory mapped
+ region.
+- interrupts: interrupt number
+- clocks: clock specifiers
+- clock-names: "aclk_crypto" used to clock data
+ "hclk_crypto" used to clock data
+ "srst_crypto" used to clock crypto accelerator
+ "apb_pclk" used to clock dma
+-status: Enable
+
+Examples:
+
+ crypto: cypto-controller at ff8a0000 {
+ compatible = "rockchip,crypto";
+ reg = <0xff8a0000 0x4000>;
+ interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&cru ACLK_CRYPTO>,
+ <&cru HCLK_CRYPTO>,
+ <&cru SRST_CRYPTO>,
+ <&cru ACLK_DMAC1>;
+
+ clock-names = "aclk_crypto",
+ "hclk_crypto",
+ "srst_crypto",
+ "apb_pclk";
+ status = "okay";
