   1Picochip picoXcell SPAcc (Security Protocol Accelerator) bindings
   2
   3Picochip picoXcell devices contain crypto offload engines that may be used for
   4IPSEC and femtocell layer 2 ciphering.
   5
   6Required properties:
   7  - compatible : "picochip,spacc-ipsec" for the IPSEC offload engine
   8    "picochip,spacc-l2" for the femtocell layer 2 ciphering engine.
   9  - reg : Offset and length of the register set for this device
  10  - interrupt-parent : The interrupt controller that controls the SPAcc
  11    interrupt.
  12  - interrupts : The interrupt line from the SPAcc.
  13  - ref-clock : The input clock that drives the SPAcc.
  14
  15Example SPAcc node:
  16
  17spacc@10000 {
  18        compatible = "picochip,spacc-ipsec";
  19        reg = <0x100000 0x10000>;
  20        interrupt-parent = <&vic0>;
  21        interrupts = <24>;
  22        ref-clock = <&ipsec_clk>, "ref";
  23};
