-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".
