1Imagination Technologies hardware hash accelerator 2 3The hash accelerator provides hardware hashing acceleration for 4SHA1, SHA224, SHA256 and MD5 hashes 5 6Required properties: 7 8- compatible : "img,hash-accelerator" 9- reg : Offset and length of the register set for the module, and the DMA port 10- interrupts : The designated IRQ line for the hashing module. 11- dmas : DMA specifier as per Documentation/devicetree/bindings/dma/dma.txt 12- dma-names : Should be "tx" 13- clocks : Clock specifiers 14- clock-names : "sys" Used to clock the hash block registers 15 "hash" Used to clock data through the accelerator 16 17Example: 18 19 hash: hash@18149600 { 20 compatible = "img,hash-accelerator"; 21 reg = <0x18149600 0x100>, <0x18101100 0x4>; 22 interrupts = <GIC_SHARED 59 IRQ_TYPE_LEVEL_HIGH>; 23 dmas = <&dma 8 0xffffffff 0>; 24 dma-names = "tx"; 25 clocks = <&cr_periph SYS_CLK_HASH>, <&clk_periph PERIPH_CLK_ROM>; 26 clock-names = "sys", "hash"; 27 };
