-Exynos True Random Number Generator

-Required properties:
-
-- compatible  : Should be "samsung,exynos5250-trng".
-- reg         : Specifies base physical address and size of the registers map.
-- clocks      : Phandle to clock-controller plus clock-specifier pair.
-- clock-names : "secss" as a clock name.

-Example:
-

How about copying description from above into the description: property?

But what to copy? There is no description except generic clock bindings.

ditto.

The same, I have no clue what to copy. It's obvious that reg contains
"physical address and size of the registers map".
