+OMAP SoC HWRNG Module
|
|
+
|
|
+Required properties:
|
|
+
|
|
+- compatible : Should contain entries for this and backward compatible
|
|
+ RNG versions:
|
|
+ - "ti,omap2-rng" for OMAP2.
|
|
+ - "ti,omap4-rng" for OMAP4, OMAP5 and AM33XX.
|
|
+ Note that these two versions are incompatible.
|
|
+- ti,hwmods: Name of the hwmod associated with the RNG module
|
|
+- reg : Offset and length of the register set for the module
|
|
+- interrupts : the interrupt number for the RNG module.
|
|
+ Only used for "ti,omap4-rng".
|
|
+
|
|
+Example:
|
|
+/* AM335x */
|
|
+rng: rng@48310000 {
|
|
+ compatible = "ti,omap4-rng";
|
|
+ ti,hwmods = "rng";
|
|
+ reg = <0x48310000 0x2000>;
|
|
+ interrupts = <111>;
|
|
+};
