* STMicroelectronics STM32 CRC

Required properties:
- compatible: Should be "st,stm32f7-crc".
- reg: The address and length of the peripheral registers space
- clocks: The input clock of the CRC instance

Optional properties: none

Example:

crc: crc@40023000 {
	compatible = "st,stm32f7-crc";
	reg = <0x40023000 0x400>;
	clocks = <&rcc 0 12>;
};
