-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";
-};
