2025-06-11reset: stm32mp25: add stm32mp25 reset driverGabriel Fernandez
Implement STM32MP25 reset drivers using stm32-core-reset API. This reset stm32-reset-core API and will be able to use DT binding index started from 0. This patch also moves legacy reset into stm32 directory reset.

2018-07-20misc: stm32: Add STM32MP1 supportPatrick Delaunay
Following next kernel rcc bindings, we must use a MFD RCC driver which is able to bind both clock and reset drivers. We can reuse and adapt RCC MFD driver already available for MCU SoCs (F4/F7/H7).

2018-05-08clk: clk_stm32f: Use PLLSAIP as USB 48MHz clockPatrice Chotard
On all STM32F4 and F7 SoCs family (except STM32F429), PLLSAI output P can be used as 48MHz clock source for USB and SDMMC. Signed-off-by: Patrice Chotard <[email protected]> Tested By: Bruno Herrera <[email protected]>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <[email protected]>

2017-11-29clk: clk_stm32fx: add clock configuration for mmc usagePatrice Chotard
MMC block needs 48Mhz source clock, for that we choose to select the SAI PLL. Update also stm32_clock_get_rate() to retrieve the MMC clock source needed in MMC driver. STM32F4 uses a different RCC variant than STM32F7. For STM32F4 sdmmc clocks bit are located into dckcfgr register whereas there are located into dckcfgr2 registers on STM32F7. In both registers, bits CK48MSEL and SDMMC1SEL are located at the same position.

2017-11-29dm: misc: bind STM32F4/F7 clock from rcc MFD driverPatrice Chotard
Like STM32H7, now STM32F4/F7 clock drivers are binded by MFD stm32_rcc driver. This also allows to add reset support to STM32F4/F7 SoCs family. As Reset driver is not part of SPL supported drivers, don't bind it in case of SPL to avoid that stm32_rcc_bind() returns an error.
