-Device-Tree bindings for Mediatek random number generator
-found in MediaTek SoC family
-
-Required properties:
-- compatible	    : Should be
-			"mediatek,mt7622-rng", 	"mediatek,mt7623-rng" : for MT7622
-			"mediatek,mt7629-rng",  "mediatek,mt7623-rng" : for MT7629
-			"mediatek,mt7623-rng" : for MT7623
-			"mediatek,mt8516-rng", "mediatek,mt7623-rng" : for MT8516
-- clocks	    : list of clock specifiers, corresponding to
-		      entries in clock-names property;
-- clock-names	    : Should contain "rng" entries;
-- reg 		    : Specifies base physical address and size of the registers
-
-Example:
-
-rng: rng@1020f000 {
-	compatible = "mediatek,mt7623-rng";
-	reg = <0 0x1020f000 0 0x1000>;
-	clocks = <&infracfg CLK_INFRA_TRNG>;
-	clock-names = "rng";
-};
