1*4882a593SmuzhiyunPicochip picoXcell SPAcc (Security Protocol Accelerator) bindings
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunPicochip picoXcell devices contain crypto offload engines that may be used for
4*4882a593SmuzhiyunIPSEC and femtocell layer 2 ciphering.
5*4882a593Smuzhiyun
6*4882a593SmuzhiyunRequired properties:
7*4882a593Smuzhiyun  - compatible : "picochip,spacc-ipsec" for the IPSEC offload engine
8*4882a593Smuzhiyun    "picochip,spacc-l2" for the femtocell layer 2 ciphering engine.
9*4882a593Smuzhiyun  - reg : Offset and length of the register set for this device
10*4882a593Smuzhiyun  - interrupts : The interrupt line from the SPAcc.
11*4882a593Smuzhiyun  - ref-clock : The input clock that drives the SPAcc.
12*4882a593Smuzhiyun
13*4882a593SmuzhiyunExample SPAcc node:
14*4882a593Smuzhiyun

16*4882a593Smuzhiyun	compatible = "picochip,spacc-ipsec";
17*4882a593Smuzhiyun	reg = <0x100000 0x10000>;
18*4882a593Smuzhiyun	interrupt-parent = <&vic0>;
19*4882a593Smuzhiyun	interrupts = <24>;
20*4882a593Smuzhiyun	ref-clock = <&ipsec_clk>, "ref";
