-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.
