+Required properties:
+- compatible: Should be "rockchip,rk3288-crypto"
+- reg: base physical address of the engine and length of memory mapped
+ region
+- interrupts: interrupt number
+- clocks: reference to the clocks about crypto
+- clock-names: "aclk" used to clock data
+ "hclk" used to clock data
+ "srst" used to clock crypto accelerator
+ "apb_pclk" used to clock dma

+Examples:

+ crypto: cypto-controller@...a0000 {
+ compatible = "rockchip,rk3288-crypto";
+ reg = <0xff8a0000 0x4000>;
+ interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>;
