* 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>;
|
|
};
