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";
|
};
