+* 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@...60000 {
+	compatible = "st,stm32f756-cryp";
+	reg = <0x50060000 0x400>;
+	interrupts = <79>;
+	clocks = <&rcc 0 STM32F7_AHB2_CLOCK(CRYP)>;
+	resets = <&rcc STM32F7_AHB2_RESET(CRYP)>;
