+Rockchip Electronics And Security Accelerator
+
+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
+ "sclk" used to clock crypto accelerator
+ "apb_pclk" used to clock dma
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the name "crypto-rst".
+
+Examples:
+
+ crypto: cypto-controller@ff8a0000 {
+ compatible = "rockchip,rk3288-crypto";
+ reg = <0xff8a0000 0x4000>;
+ interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&cru ACLK_CRYPTO>, <&cru HCLK_CRYPTO>,
+ <&cru SCLK_CRYPTO>, <&cru ACLK_DMAC1>;
+ clock-names = "aclk", "hclk", "sclk", "apb_pclk";
+ resets = <&cru SRST_CRYPTO>;
+ reset-names = "crypto-rst";
+ status = "okay";
+ };
