b11289997f drivers/clock_control: Add support to stm32wb series
Add support to stm32wb series in stm32 clock_control driver.
Ip is similar to stm32l4 one but AHB bus presacler is renamed
to "CPU1" and CPU2 and AHB4 prescalers should be defined.

db90e24326 drivers: nrf: add support for forcing driver implementation
An external project extending the Zephyr RTOS and its drivers may have
subsystems that must use its own specific driver(s) when active. One
example is the nRF5x NVMC that must be scheduled in between radio
operations. A subsystem may also be dependent on its own drivers for
security, real-time and/or because of hardware constrains.

In order to not introduce non-Zephyr specific code into the Zephyr tree,
an option is added to disable the in-tree drivers in Zephyr. Because
Kconfig does not support a good way of de-selecting other symbols, a
variable on the form `<DRIVER>_FORCE_ALT` is added as a
dependency for each `<DRIVER>`. For example, the out-of-tree subsystem
will select `FLASH_NRF_FORCE_ALT` to disable the in-tree driver. A
solution for issue #8181 would open up for a more general solution,
however #8181 requires significant effort.

Support for out-of-tree drivers is added to Nordic drivers for
clock_control, entropy and flash.

A generic solution for this is desired. Issue #14527 is tracking that
progress.

0cfb2fad29 kconfig: drivers: clock_control: Remove redundant CLOCK_CONTROL deps.
These symbols appear within an 'if CLOCK_CONTROL' (in
drivers/clock_control/Kconfig).

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.

Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

cb53a1a2d5 drivers: clock_control: Remove asserts that break LF clock on nRF5
There are two asserts in the ISR for clock events on the nRF5 that
appear to be accidental.

The first assert fails if there are any LF clock started events, which
there will be when starting up the RC oscillator with calibration.

The second assert fails when we decrement the refcount on the HF
oscillator after finishing a calibration. There will typically be
users left of the HF oscillator, so _m16src_stop() doesn't actually
stop it and thus doesn't return 0.

This code typically works fine because it's not built with asserts
enabled by default. Can be reproduced on a BBC microbit with the
default config plus CONFIG_ASSERT=y.

39d63d316b clock_control: Add support for getting LPO frequency in mcux sim driver
The mcux sim clock control driver was originally designed to pass
through the clock subsystem value from dts to the mcux CLOCK_GetFreq()
function. This assumed that the values in
include/dt-bindings/clock/kinetis_sim.h matched the enumeration in
fsl_clock.h, which is true for the coresys, platform, and bus clocks.
However, the low-power oscillator (LPO) clock has a different values in
k64 vs. kw2xd, therefore we must update the clock_control driver to
parse the value from dts and convert it to the fsl_clock.h enumeration.

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.

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

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.

5843e8df89 drivers: clock_control: Add nRF5x Series SoC clock driver
In the Nordic Semiconductor's nRF5x series SoC clock control
system can source the system clocks from a range of internal or
external high and low frequency oscillators and distribute them
to modules based upon a module’s individual requirements.
In this commit the implementation adds support for 16MHz
peripheral clock, 32.768 kHz RC oscillator, and 32.768 kHz
crystal oscillator clock sources.

16MHz peripheral clock is required to use the 2.4GHz Radio
peripheral. 32.768 kHz RC or crystal oscillator clock source
is required to use the real time counter peripheral.

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.

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.

14482f0940 clock_control: extend API with clock rate query operation
Extend the public API of clock_control driver with a function for
querying of clock rate driving given peripheral. This is useful when the
driver must calculate or configurae values that depend on the rate of
clock driving this subsystem.

A baud rate setting of UART port is an example of such operation. To
configure a particular baud rate the driver may need to set the internal
counters of UART port, where the actual value will depend on the clock
rate for this peripheral.

The implementation returns DEV_NO_SUPPORT for clock_control drivers that
do not implement such functionality.

Note: such clock has _nothing_ to do with a Real Time Clock (RTC).
