1*c66ec88fSEmmanuel VadotPicochip picoXcell SPAcc (Security Protocol Accelerator) bindings
2*c66ec88fSEmmanuel Vadot
3*c66ec88fSEmmanuel VadotPicochip picoXcell devices contain crypto offload engines that may be used for
4*c66ec88fSEmmanuel VadotIPSEC and femtocell layer 2 ciphering.
5*c66ec88fSEmmanuel Vadot
6*c66ec88fSEmmanuel VadotRequired properties:
7*c66ec88fSEmmanuel Vadot  - compatible : "picochip,spacc-ipsec" for the IPSEC offload engine
8*c66ec88fSEmmanuel Vadot    "picochip,spacc-l2" for the femtocell layer 2 ciphering engine.
9*c66ec88fSEmmanuel Vadot  - reg : Offset and length of the register set for this device
10*c66ec88fSEmmanuel Vadot  - interrupts : The interrupt line from the SPAcc.
11*c66ec88fSEmmanuel Vadot  - ref-clock : The input clock that drives the SPAcc.
