+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>;
Please rewrite the description of interrupts property sa follows:
- interrupts : interrupt specifiers of SSS module interrupts, should
contain two entries:
- first : feed control interrupt,
- second : hash interrupt.
Then in later patch adding support for Exynos, it shoudl be rewritten to:
- interrupts : interrupt specifiers of SSS module interrupts, should
contain following entries:
- first : feed control interrupt (required for all variants),
- second : hash interrupt (required only for samsung,s5pv210-secss).
Best regards,
Tomasz
