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
Optional properties:
- resets : The reset to properly start RNG
- clock-error-detect : Enable the clock detection management
Example:
rng: rng@50060800 {
compatible = "st,stm32-rng";
reg = <0x50060800 0x400>;
interrupts = <80>;
clocks = <&rcc 0 38>;
};
