Samsung SoC SlimSSS (Slim Security SubSystem) module
The SlimSSS module in Exynos5433 SoC supports the following:
-- Feeder (FeedCtrl)
-- Advanced Encryption Standard (AES) with ECB,CBC,CTR,XTS and (CBC/XTS)/CTS
-- SHA-1/SHA-256 and (SHA-1/SHA-256)/HMAC
Required properties:
- compatible : Should contain entry for slimSSS version:
- "samsung,exynos5433-slim-sss" for Exynos5433 SoC.
- reg : Offset and length of the register set for the module
- interrupts : interrupt specifiers of SlimSSS 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 "pclk" and
"aclk" for slim-sss in Exynos5433.

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".
