* STMicroelectronics STM32 CRYP
Required properties:
- compatible: Should be "st,stm32f756-cryp".
- reg: The address and length of the peripheral registers space
- clocks: The input clock of the CRYP instance
- interrupts: The CRYP interrupt
Optional properties:
- resets: The input reset of the CRYP instance
Example:
crypto@50060000 {
compatible = "st,stm32f756-cryp";
reg = <0x50060000 0x400>;
interrupts = <79>;
clocks = <&rcc 0 STM32F7_AHB2_CLOCK(CRYP)>;
resets = <&rcc STM32F7_AHB2_RESET(CRYP)>;
};
