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";

};
