 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,

 - reg : Offset and length of the register set for the module
 - interrupts : interrupt specifiers of SSS module interrupts, should contain
-               two entries:
-               - first : feed control interrupt,
-               - second : hash interrupt.
+               following entries:
+               - first : feed control interrupt (required for all variants),
+               - second : hash interrupt (required only for samsung,s5pv210-secss).
