Kernel-4.18.0-80.el8_img-hash

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";
};
