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";
};
