[PATCH 00/10] hwrng: stm32: support STM32MP13x platforms

[Gatien Chevallier]

The STM32MP13x platforms have a RNG hardware block that supports
customization, a conditional reset sequences that allows to
recover from certain situations and a configuration locking
mechanism.

This series adds support for the mentionned features. Note that
the hardware RNG can and should be managed in the secure world
for this platform, hence the rng not being default enabled on
the STM32MP135F-DK board. 

Gatien Chevallier (10):
  dt-bindings: rng: introduce new compatible for STM32MP13x
  hwrng: stm32 - use devm_platform_get_and_ioremap_resource() API
  hwrng: stm32 - implement STM32MP13x support
  hwrng: stm32 - implement error concealment
  hwrng: stm32 - rework error handling in stm32_rng_read()
  hwrng: stm32 - restrain RNG noise source clock
  dt-bindings: rng: add st,rng-lock-conf
  hwrng: stm32 - support RNG configuration locking mechanism
  hwrng: stm32 - rework power management sequences
  ARM: dts: stm32: add RNG node for STM32MP13x platforms
