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.
