+Device-Tree bindings for Mediatek random number generator
+found in Mediatek SoC family
+
+Required properties:
+- compatible : Should be "mediatek,mt7623-rng"
+- 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";
+};
