| 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"; | 
 | }; |
