[PATCH v2 0/7] rng: stm32: support STM32MP13x platforms

[Gatien Chevallier]

This is the cover letter for patchset [1].
First, do not restrain the STM32 RNG driver to the MPU series.

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.

Changes in V2:
	- Added this cover letter
	- Added ARCH_STM32 as a dependency for RNG_STM32
	- Added review tags

Gatien Chevallier (7):
  rng: stm32: rename STM32 RNG driver
