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 = ; dmas = <&dma 8 0xffffffff 0>; dma-names = "tx"; clocks = <&cr_periph SYS_CLK_HASH>, <&clk_periph PERIPH_CLK_ROM>; clock-names = "sys", "hash"; };
