- 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";
- };
