Subject: [PATCH v6 0/5] Introduce STM32MP257 clock driver

From: Gabriel Fernandez <gabriel.fernandez@...s.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

v6:
  - remove useless defines in drivers/clk/stm32/stm32mp25_rcc.h

v5:
  - Fix sparse warnings: was not declared. Should it be static?
    drivers/clk/stm32/clk-stm32mp13.c:1516:29: symbol 'stm32mp13_reset_data'
    drivers/clk/stm32/clk-stm32mp1.c:2148:29: symbol 'stm32mp1_reset_data'
    drivers/clk/stm32/clk-stm32mp25.c:1003:5: symbol 'stm32mp25_cpt_gate'
    drivers/clk/stm32/clk-stm32mp25.c:1005:29: symbol 'stm32mp25_clock_data'
    drivers/clk/stm32/clk-stm32mp25.c:1011:29: symbol 'stm32mp25_reset_data'

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

Gabriel Fernandez (5):
  clk: stm32mp1: move stm32mp1 clock driver into stm32 directory
  clk: stm32mp1: use stm32mp13 reset driver
  dt-bindings: stm32: add clocks and reset binding for stm32mp25
    platform
  clk: stm32: introduce clocks for STM32MP257 platform
  arm64: dts: st: add rcc support in stm32mp251
