[PATCH v4 0/5] Introduce STM32MP257 clock driver

[gabriel.fernandez]

From: Gabriel Fernandez <gabriel.fernandez@foss.st.com>

This patch-set introduces clock driver for STM32MP257 based on Arm Cortex-35.
It creates also a menuconfig for all STM32MP clock drivers.
The STM32MP1 and STM32MP13 are now in same stm32 directory

v4:
  - use GPL-2.0-only OR BSD-2-Clause for clock and reset binding files
  - use quotes ' for #clock-cells and #reset-cells in YAML documentation
  - reset binding start now to 0 instead 1
  - improve management of reset lines that are not managed 

v3:
  - from Rob Herring change clock item description in YAML documentation
v2:
  - rework reset binding (use ID witch start from 0)
  - rework reset driver to manage STM32MP13 / STM32MP15 / STM32MP25
  - rework YAML documentation

[PATCH v4 2/5] clk: stm32mp1: use stm32mp13 reset driver

[gabriel.fernandez]

From: Gabriel Fernandez <gabriel.fernandez@foss.st.com>

STM32MP15 is now using the same reset driver as STM32MP13 as they
have the same binding requirement.
