+* AMD Cryptographic Coprocessor driver (ccp)
+
+Required properties:
+- compatible: Should be "amd,ccp-seattle-v1a"
+- reg: Address and length of the register set for the device
+- interrupt-parent: Should be the phandle for the interrupt controller
+ that services interrupts for this device
+- interrupts: Should contain the CCP interrupt
+
+Example:
+ ccp@e0100000 {
+ compatible = "amd,ccp-seattle-v1a";
+ reg = <0 0xe0100000 0 0x10000>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 3 4>;
