Subject: [PATCH 0/3] hwrng: stm32 - add support for STM32 HW RNG

This patchset introduces a driver for the STM32 hardware random number
generator.

v2:

 * Moved binding docs from .../hwrng/ to .../rng/ and renamed to match
   convention in new directory (Rob Herring).
 * Adopted runtime PM and auto-suspend instead of managing the clocks
   from the read function (Linus Walleij). Increased bandwidth by ~30%.
 * Simplified error detection in main read loop (Linus Walleij, Maxime
   Coquelin).
 * Only WARN_ONCE() when hardware failure mechanisms trigger (Maxime
   Coquelin).
 * Simplify end of probe function after cocci warning (Fengguang Wu).
 * Switch to devm_hwrng_register.
