The STM32 GPIO driver extended the generic GPIO driver interace with
the concept of OPEN_DRAIN. There is previous discussion about
representing such concepts in the GPIO interface in a more general
fashion here:

The DRIVE STRENGTH interface supports the concepts of OPEN DRAIN and

Most of the SoC and board Kconfig use the same values for
driver initialization priorities. So refactor them, and
discard duplicate ones.
The shared IRQ init priority was changed so that the kernel
default init and device init priorities can be standardized
across all SoC/boards. Same goes for DesignWare SPI driver.
This also changes the UART_CONSOLE_PRIORITY and
IPM_CONSOLE_PRIORITY to UART_CONSOLE_INIT_PRIORITY and
IPM_CONSOLE_INIT_PRIORITY, to standardize across all drivers.
Note that this does not take away the ability to override
those values. This just provides reasonable defaults such
that there is virtually no need to override.

There are two major issues with the kconfig:
() Some of the config options have incorrect dependencies inside help
under menuconfig. For example, CONFIG_GPIO depends on BOARD_GALILEO.
() Since the SoC and board specific kconfig files are parsed first,
the help screen would say, for example, CONFIG_SPI is defined at
arch/arm/soc/fsl_frdm_k64f/Kconfig. This is incorrect because
the actual config is defined in drivers/spi/Kconfig.
These cause great confusion to users of menuconfig/xconfig.
To fix these, the SoC and board defaults are now to be parsed last.
Note that the position swapping of defaults in this patch is due to
the fact the the default parsed last will be used.
And, spi_test is broken due to the fact that it requires
CONFIG_SPI_INTEL_PORT_1, but never enables it anywhere. This is
bypassed for now.

The patch adds a driver for STM32F10x series RCC (Reset and Clock
Control) subsystem.
The module is primarily responsible for setting up of MCU's clock
tree. In particular the driver sets up SYSCLK, PLL (with source
configuration), AHB prescaler, and APB1/APB2 prescalers. As part of this
functionality, the subsystem can enable/disable clock signal for
particular peripherals, thus reducing the power consumption of the MCU.
The driver implements clock control driver API. However, subsystem IDs
being HW specific are exposed in driver public header that must be
included by callers. The driver registers a single device using a common
name STM32_CLOCK_CONTROL_NAME. The device is initialized at
the PRIMARY level with priority 1. This allows the initialization to
take place right after SoC initialization routine.
The driver depends on selection of SOC_STM32F1X config option and is MCU
specific.

The patch introduces a new family of SoCs based on STMicroelectronics'
STM32 MCU line. The patch introduces a basic arch/arm/soc layout along
with configuration of 2 MCUs from STM32F1 series: STM32F103VE and
STM32F103RB.
The patch assumes that other MCUs from STM32 family will be included
under arch/arm/soc/st_stm32 tree, to achieve the following layout:
arch/
arm/
soc/
st_stm32/
stm32f0/
stm32f1/
stm32f2/
...
stm32l0/
Most of the configuration within a single MCU family (ex. STM32F1) is
shared, however individual MCUs differ with respect to SRAM size, flash
size or the number of available peripherals. The patch assumes that per
MCU line Kconfig.soc.family file should introduce basic setup for given
series. This can be further tuned by per MCU files, with
Kconfig.soc.stm32f103rb and Kconfig.soc.stm32f103ve as examples.
Each family defines a configuration option, ex. CONFIG_STM32F10X, while
individual MCUs define a corresponding per MCU config options,
ex. CONFIG_STM32F103VE.
From the menuconfig perspective, the user is presented with a family
selection under General Platform Configuration/SoC Selection. A
specific MCU model can be selected by accessing General Platform
Configuration/STM32F1x MCU Selection, with the default entry being
selected by the board configuration.
