+OMAP ROM RNG driver binding
+
+Secure SoCs may provide RNG via secure ROM calls like Nokia N900 does. The
+implementation can depend on the SoC secure ROM used.
+
+- compatible:
+ Usage: required
+ Value type: <string>
+ Definition: must be "nokia,n900-rom-rng"
+
+- clocks:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: reference to the the RNG interface clock
+
+- clock-names:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "ick"
+
+Example:
+
+ rom_rng: rng {
+ compatible = "nokia,n900-rom-rng";
+ clocks = <&rng_ick>;
+ clock-names = "ick";
+ };
