Kernel-4.18.0-80.el8_st,stm32-hash

• STMicroelectronics STM32 HASH

Required properties:

• compatible: Should contain entries for this and backward compatible
  HASH versions:
  • “st,stm32f456-hash” for stm32 F456.
  • “st,stm32f756-hash” for stm32 F756.
• reg: The address and length of the peripheral registers space
• interrupts: the interrupt specifier for the HASH
• clocks: The input clock of the HASH instance

Optional properties:

• resets: The input reset of the HASH instance
• dmas: DMA specifiers for the HASH. See the DMA client binding,
  Documentation/devicetree/bindings/dma/dma.txt
• dma-names: DMA request name. Should be “in” if a dma is present.
• dma-maxburst: Set number of maximum dma burst supported

Example:

hash1: hash@50060400 {
compatible = “st,stm32f756-hash”;
reg = <0x50060400 0x400>;
interrupts = <80>;
clocks = <&rcc 0 STM32F7_AHB2_CLOCK(HASH)>;
resets = <&rcc STM32F7_AHB2_RESET(HASH)>;
dmas = <&dma2 7 2 0x400 0x0>;
dma-names = “in”;
dma-maxburst = <0>;
};
