Vincenzo Frascino 86add71a86 clock_control: Cleanup stm32f10x driver
This patch addresses the following issues:
* Aligns the Kconfig code style with Zephyr projects requirements.
* Removes redundant "depends on" from Kconfig.
* Adds static to the containing file scope declarations.

Andrew Boie 0b474eef9c kernel: deprecate old init levels
PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.

New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.

Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

Erwan Gouriou eed678612b clock_control: have FLASH_BASE compatible with ST CMSIS files
In ST CMSIS files, FLASH_BASE does not mean base address of FLASH register
Instead FLASH_R_BASE is used.
stm32f1 clock control driver is updated to be compatible with this naming.

Daniel Leung 546b8ade37 refactor common driver initialization priorities
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.

Maciek Borzecki 61c0363257 clock_control/stm32f1: HSE support and PLL configuration cleanup
Add support for use of HSE (incorrectly named PREDIV1)as input of PLL,
along with HSE bypass for stabilized external clock, and XTPRE
prescaler. Update PLL handling so that we do not unnecessarily enable
PLL clocks, instead enabling only the clocks sources that are required
as per user's configuration.

This change allows higher SYSCLK clock values, up to 72MHz.

Andre Guedes 024cfe754e drivers: Replace DEV_OK by 0
This patch replaces all occurences of the macro DEV_OK by the actual
value 0 at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/.

This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

Maciek Borzecki 3f5af00529 clock_control/stm32f10x: introduce driver for STM32F10x RCC
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.
