Subject: [PATCH 0/4] Add support for stm32mp25x RNG

This patchset adds support for the Random Number
Generator(RNG) present on the stm32mp25x platforms.
On these platforms, the clock management and the RNG
parameters are different.

While there, update the RNG max clock frequency on
stm32mp15 platforms according to the latest specs.

Tested on the stm32mp257f-ev1 platform with a deep
power sequence with rngtest before/after the sequence with
satisfying results.

Same was done on stm32mp135f-dk to make sure no regression was added.

On stm32mp157c-dk2, I didn't perform a power sequence but the rngtest
results were satisfying.

Gatien Chevallier (4):
  dt-bindings: rng: add st,stm32mp25-rng support
  hwrng: stm32 - implement support for STM32MP25x platforms
  hwrng: stm32 - update STM32MP15 RNG max clock frequency
  arm64: dts: st: add RNG node on stm32mp251
