-Amlogic Meson Random number generator
-=====================================
-
-Required properties:
-
-- compatible : should be "amlogic,meson-rng"
-- reg : Specifies base physical address and size of the registers.
-
-Optional properties:
-
-- clocks : phandle to the following named clocks
-- clock-names: Name of core clock, must be "core"
-
-Example:
-
-rng {
-	compatible = "amlogic,meson-rng";
-	reg = <0x0 0xc8834000 0x0 0x4>;
-	clocks = <&clkc CLKID_RNG0>;
-	clock-names = "core";
-};
