39bb93d402 drivers: stm32 clock control: fix HSI PLLSOURCE with PREDIV1 support
The combination of
CONFIG_CLOCK_STM32_SYSCLK_SRC_PLL and
CONFIG_CLOCK_STM32_PLL_SRC_HSI
on SOCs with PREDIV1 support made use of the LL define
LL_RCC_PLLSOURCE_HSI_DIV_2, which is not defined for SOCs with
PREDIV1 support.

This exchanges LL_RCC_PLLSOURCE_HSI_DIV_2 with LL_RCC_PLLSOURCE_HSI
which is the appropiate source according to stm32f0xx_ll_rcc.h
line 473 and stm32f3xx_ll_rcc.h line 795.

Tested by compiling hello world for nucleo_f091rc board with HSI as
PLLSOURCE.

12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make

Adds a new clock control driver for Kinetis SoCs that have the system
integration (SIM) module. This will allow mcux shim drivers, such as
uart and i2c, to abstract the call to CLOCK_GetFreq() behind the
clock_control interface and thus be reused for SoCs with different clock

1d8c8ac3af clock_control: nrf5_power: Let the LF clock be configured at least once
If the LF clock was already started, but wasn't initialized with
_k32src_start yet, allow it to run once. This is needed because if a
soft reset is triggered while watchdog is active, the LF clock will
already be running, but won't be configured yet (watchdog forces LF
clock to be running).

If the LF clock isn't configured with _k32src_start, the nRF5 RTC
won't count and the whole system will malfunction, as the kernel
depends on the clock source being working properly.

15780bd542 clock_control: stm32: fix a PLL init corner case
Commit 58c8d15 ("clock control:stm32: provide STM32Cube LL based
driver") added PLL initialization which disables the PLL before
configuring it.

This works if the system clock source is not the PLL (which is the
usual case for Zephyr booting out of chip reset). However, if the
SYSCLK source *is* the PLL, this halts execution.

To support this use case, switch the SYSCLK source to the
always-present HSI before disabling the PLL.

58c8d15147 clock control:stm32: provide STM32Cube LL based driver
This new clock control driver aims at providing a lightweight
generic driver to the whole stm32 family.
Driver is based on LL Cube API and hence is for now available
only for STM32 supporting this API: stm32f3xx and stm32l4xx.
Other families should be supported soon.
Once globally supported, this unique driver will also help
reducing the impact of stm32 clock control heterogeneity in
other drivers.
