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"; |
|
};
