2021-01-13misc: rcc: keep the rcc device name for subnodePatrick Delaunay1-2/+2
Update the name associated with the RCC drivers to avoid duplicated name with the driver name. With this patch the traces displayed with log macro provide a correct device name. The rcc device name before the patch is: Class Index Probed Driver Name ----------------------------------------------------------- root 0 [ + ] root_driver root_driver simple_bus 0 [ + ] simple_bus |-- soc (...) nop 0 [ + ] stm32-rcc | |-- rcc@50000000 clk 0 [ + ] stm32mp1_clk | | |-- stm32mp1_clk reset 0 [ + ] stm32_rcc_reset | | `-- stm32_rcc_reset And they become: (...) nop 0 [ + ] stm32-rcc | |-- rcc@50000000 clk 0 [ + ] stm32mp1_clk | | |-- rcc@50000000 reset 0 [ + ] stm32_rcc_reset | | `-- rcc@50000000 The traces is correct: stm32mp1_clk rcc@stm32mp1_clk: ..... => stm32mp1_clk rcc@50000000: .....

2020-02-06dm: core: Create a new header file for 'compat' featuresSimon Glass1-0/+1
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-08-27misc: change RCC form MISC to NOP uclassPatrick Delaunay1-4/+1
The RCC driver have no operation so the new NOP uclass is more appropriate. It only used as parent for clock and reset driver. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2018-07-20misc: stm32: Add STM32MP1 supportPatrick Delaunay1-4/+15
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).

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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 <trini@konsulko.com>
2017-11-30dm: misc: bind STM32F4/F7 clock from rcc MFD driverPatrice Chotard1-5/+37
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.

2017-09-22dm: misc: add stm32 rcc driverChristophe Kerello1-0/+45
This patch adds the support of reset and clock control block (rcc) found on STM32 SoCs. This driver is similar to a MFD linux driver. This driver supports currently STM32H7 only. STM32F4 and STM32F7 will be migrated to this rcc MFD driver in the future to uniformize all STM32 SoCs already upstreamed.
