[PATCH 1/3] dt-bindings: Document the STM32 HW RNG bindings

From: Daniel Thompson <hidden>
Date: 2015-10-12 08:23:17
Also in: linux-crypto, linux-devicetree, lkml
Subsystem: hardware random number generator core, open firmware and flattened device tree bindings, the rest · Maintainers: Olivia Mackall, Herbert Xu, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

This adds documentation of device tree bindings for the STM32 hardware
random number generator.

+STMicroelectronics STM32 HW RNG
+===============================
+
+The STM32 hardware random number generator is a simple fixed purpose IP and
+is fully separated from other crypto functions.
+
+Required properties:
+
+- compatible : Should be "st,stm32-rng"
+- reg : Should be register base and length as documented in the datasheet
+- interrupts : The designated IRQ line for the RNG
+- clocks : The clock needed to enable the RNG
+
+Example:
+
+	rng: rng at 50060800 {
+		compatible = "st,stm32-rng";
+		reg = <0x50060800 0x400>;
+		interrupts = <80>;
+		clocks = <&rcc 0 38>;
+	};
