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";
};
