    +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".
