From: gabriel.fernandez
Date: Tue Apr 09 2024 - 13:15:13 EST


From: Gabriel Fernandez <gabriel.fernandez@xxxxxxxxxxx>

v10:
- patch 'dt-bindings: stm32: update DT bingding for stm32mp25'
- cosmetic change (add change blank line) to YAML documentation
- rename USB2 into USBH to be compliant with last Reference Manuel
- Update commit message
cant't add 'Acked-by: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>' because modification above

- patch 'clk: stm32: introduce clocks for STM32MP257 platform'
- rename USB2 into USBH to be compliant with last Reference Manuel
- cosmetic changes to be aligned with open parenthesis.

v9: base on next-20240207
- update dt binding documentation with v8 modidification on RCC driver
(use .index of clk_parent_data struct to define a parent)
- rebase patch "arm64: dts: st: add rcc support for STM32MP25"
with next-20240207 tag

v8:
- use .index of clk_parent_data struct to define a parent
- remove unnecessary dependency check with SCMI clock driver
- convert to platform device APIs
- convert to devm_of_clk_add_hw_provider()
- convert single value enum to a define

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
