| 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"; |
| }; |
