+Samsung SoC SSS (Security SubSystem) module
+
+The SSS module in S5PV210 SoC supports the following:
+-- Feeder (FeedCtrl)
+-- Advanced Encryption Standard (AES)
+-- Data Encryption Standard (DES)/3DES
+-- Public Key Accelerator (PKA)
+-- SHA-1/SHA-256/MD5/HMAC (SHA-1/SHA-256/MD5)/PRNG
+-- PRNG: Pseudo Random Number Generator
+
+Required properties:
+
+- compatible : Should contain entries for this and backward compatible
+  SSS versions:
+  - "samsung,s5pv210-secss" for S5PV210 SoC.
+- reg : Offset and length of the register set for the module
+- interrupts : the interrupt-specifier for the SSS module.
+		Two interrupts "feed control and hash" in case of S5PV210
+	   Eg : interrupts = <0 feed-control 0> <0 hash 0>;
