-* 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>;
