-* Microchip PIC32 Random Number Generator
-
-The PIC32 RNG provides a pseudo random number generator which can be seeded by
-another true random number generator.
-
-Required properties:
-- compatible : should be "microchip,pic32mzda-rng"
-- reg : Specifies base physical address and size of the registers.
-- clocks: clock phandle.
-
-Example:
-
-	rng: rng@1f8e6000 {
-		compatible = "microchip,pic32mzda-rng";
-		reg = <0x1f8e6000 0x1000>;
-		clocks = <&PBCLK5>;
