Subject: [PATCH v7 0/2] Introduce STM32MP257 clock driver

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

v7: base on next-20231219
  - These patches below are applied to clk-next:
      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
  - remove unnecessary includes
  - migrate clock parents to struct clk_parent_data and remove
    CLK_STM32_XXX() macros  to have a more readble code
  - use platform device APIs (devm_of_iomap() instead of_iomap())
  - move content of stm32mp25_rcc_init() to stm32mp25_rcc_clocks_probe()
  - simply get_clock_deps()
  - add const to stm32mp25_data struct
  - remove ck_icn_p_serc clock (will be integrate later with security
    management)

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 (2):
  clk: stm32: introduce clocks for STM32MP257 platform
  arm64: dts: st: add rcc support in stm32mp251
