1 | Imagination Technologies hardware hash accelerator |
2 | ||
3 | The hash accelerator provides hardware hashing acceleration for | |
4 | SHA1, SHA224, SHA256 and MD5 hashes | |
5 | ||
6 | Required 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 | ||
17 | Example: | |
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 | }; |
