+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 : interrupt specifiers of SSS module interrupts, should contain
+ two entries:
+ - first : feed control interrupt,
+ - second : hash 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".
