+Picochip picoXcell SPAcc (Security Protocol Accelerator) bindings
+
+Picochip picoXcell devices contain crypto offload engines that may be used for
+IPSEC and femtocell layer 2 ciphering.
+
+Required properties:
+  - compatible : "picochip,spacc-ipsec" for the IPSEC offload engine
+    "picochip,spacc-l2" for the femtocell layer 2 ciphering engine.
+  - reg : Offset and length of the register set for this device
+  - interrupt-parent : The interrupt controller that controls the SPAcc
+    interrupt.
+  - interrupts : The interrupt line from the SPAcc.
+  - ref-clock : The input clock that drives the SPAcc.
+
+Example SPAcc node:
+
+spacc@10000 {
+       compatible = "picochip,spacc-ipsec";
+       reg = <0x100000 0x10000>;
+       interrupt-parent = <&vic0>;
+       interrupts = <24>;
+       ref-clock = <&ipsec_clk>, "ref";
+};
