Before updating stm32 pinctrl/gpio drivers to support plain GPIO
feature, rework pin configuration functions headers to provide
more clarity on the arguments and the information they convey:
- pin configuration
- pin function

The function is only used by the driver itself. This likely comes from
pre-runtime PM API usage.

Make gpio32_stm32_configure use runtime PM API (so that it can be used
externally without further effort). The raw version of the function (no
PM put/get) has been introduced for internal use.

The device PM subsystem already holds the device state, so there is no
need to keep duplicates inside the device. The pm_device_state_get has
been refactored to just return the device state. Note that this is still
not safe, but the same applied to the previous implementation. This
problem will be addressed later.

Move all PM_DEVICE_STATE_* definitions to an enum. The
PM_DEVICE_STATE_SET and PM_DEVICE_STATE_GET definitions have been kept
out of the enum since they do not represent any state. However, their
name has not been changed since they will be removed soon.
All drivers and tests have been adjusted accordingly.

Now that pinmux driver holds a table of GPIO device pointers,
use gpio device as the single source of trust for gpio_base
and remove use of port_base and related code.
This way, gpio_stm32_configure could directly take gpio device
pointer as argument.

Add the common config structure as a prefix of the driver-specific
config structure. This driver uses fixups to define a common name
based on the SOC series; until aliases for the new properties are
added the code assumes all pins are supported.
Since pin ordinal validation is now done directly in gpio API,
remove checks inside the driver itself.

https://github.com/zephyrproject-rtos/ci-tools/pull/65 tweaks the check
for references to undefined Kconfig symbol to whitelist anything on the
form 'CONFIG_FOO_*' (or 'CONFIG_FOO_*_...'). This is meant for #endif
comments that talk about many related symbols.
Fix two existing #endif comments to use that format, so that some

The original implementation of gpio functions access registers
directly. Using LL library can add a set of unifying access

All series STM32 have mostly the same GPIO architecture
and can share the same code for GPIO manipulation.
Functions of the external interrupt line control are also the same.
This patch extracts common code from them and put them into the 'common'
folder.
Functions of control GPIO of these series scattered in
soc/arm/st_stm32/stm32xx/ folders contain these functions:
stm32_gpio_flags_to_conf(), stm32_gpio_configure(), stm32_gpio_set(),
stm32_gpio_get, stm32_gpio_enable_int().
This patch merges them into the gpio_stm32.c file.

ports_enable array holds port clock information.
It is populated for all SoCs, but ports availability depends on
SoCs. The way it is defined today, location of the port in the
array depends on previous ports definition in SoC CMSIS files.
Though, port index is always the same irrespective of previous
ports availability in the SoC.
This will result in incoherency between port index and clock
information.
Fix this by setting a bogus value if port is not defined.
Return an error if bogus value is read.

This commit enables STM32Cube LL based driver for stm32f4 series.
This generic driver provides a unified API to clock driver for all

LL API allows driver to be lightweight and to keep genericity across

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a

Also updated doc/porting/application.rst that had a dependency on

Manually updated subsys/logging/sys_log.c that had a malformed
