     Imagination Technologies hardware hash accelerator
     
     The hash accelerator provides hardware hashing acceleration for
     SHA1, SHA224, SHA256 and MD5 hashes
     
     Required properties:
     
     - compatible : "img,hash-accelerator"
     - reg : Offset and length of the register set for the module, and the DMA port
    - interrupts : The designated IRQ line for the hashing module.
    - dmas : DMA specifier as per Documentation/devicetree/bindings/dma/dma.txt
    - dma-names : Should be "tx"
    - clocks : Clock specifiers
    - clock-names : "sys" Used to clock the hash block registers
                    "hash" Used to clock data through the accelerator
    
    Example:
    
            hash: hash@18149600 {
            compatible = "img,hash-accelerator";
                    reg = <0x18149600 0x100>, <0x18101100 0x4>;
                    interrupts = <GIC_SHARED 59 IRQ_TYPE_LEVEL_HIGH>;
                    dmas = <&dma 8 0xffffffff 0>;
                    dma-names = "tx";
                    clocks = <&cr_periph SYS_CLK_HASH>, <&clk_periph PERIPH_CLK_ROM>;
                    clock-names = "sys", "hash";
            };
