+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
+
+The SSS module in Exynos4 (Exynos4210) and
+Exynos5 (Exynos5420 and Exynos5250) SoCs
+supports the following also:
+-- ARCFOUR (ARC4)
+-- True Random Number Generator (TRNG)
+-- Secure Key Manager
+
+Required properties:
+
+- compatible : Should contain entries for this and backward compatible
+  SSS versions:
+  - "samsung,s5pv210-secss" for S5PV210 SoC.
+  - "samsung,exynos4210-secss" for Exynos4210, Exynos4212, Exynos4412, Exynos5250,
+		Exynos5260 and Exynos5420 SoCs.
+- reg : Offset and length of the register set for the module
+- interrupts : interrupt specifiers of SSS module interrupts (one feed
+		control interrupt).
+
+- clocks : list of clock phandle and specifier pairs for all clocks  listed in
+		clock-names property.
+- clock-names : list of device clock input names; should contain one entry
+		"secss".
