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";

	};
