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";
};
