Kumar Gala 5a8a06661d drivers: gpio: cleanup select HAS_DTS_GPIO
All GPIO controller drivers support DTS so we can select HAS_DTS_GPIO
at the GPIO driver subsystem level rather than for each specific driver.

Erwan Gouriou e26767fc06 drivers/gpio: stm32: Remove Kconfig based device declaration
Use device node declaration instead.
Clean up GPIO_STM32_PORT* Kconfig symbols.

On some boards some gpio ports where disabled using Kconfig symbols.
Disable them now via device tree nodes in boards dts files.

Ulf Magnusson 378d6b137a kconfig: Replace non-defconfig single-symbol 'if's with 'depends on'
Same deal as in commit eddd98f811 ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for the remaining cases outside defconfig
files. See that commit for an explanation.

Will do the defconfigs separately in case there are any complaints
there.

Ulf Magnusson bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

    git ls-files '*Kconfig*' | \
        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

Findlay Feng 4b18a079d9 drivers: gpio: add stm32f1x SWJ configuration
Add the serial wire JTAG configuration of the stm32f1x family.
Before gpio is initialized, you can choose to turn off the debug pin to
make the used pins available.

Ulf Magnusson e65f8ba1f2 kconfig: gpio: Remove lots of redundant GPIO dependencies
Most of these are from source'ing a file within an 'if GPIO', and then
adding another 'depends on GPIO' within it.

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. 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.

Ulf Magnusson f912dfebea drivers: gpio: Kconfig: Remove redundant 'default n' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

Piggyback a missing 'source "drivers/gpio/Kconfig.imx"'. This file
wasn't included anywhere previously.

Kumar Gala 57904102fd gpio: dts: Introduce Kconfig symbols to convey GPIO dts support
Add a set of Kconfig symbols that allow us to set that the GPIO
driver/SoC support DTS (HAS_DTS_GPIO) and that drivers that need/use
GPIO support DTS as well (HAS_DTS_GPIO_DEVICE).

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Anas Nashif 9bf2da7ef4 stm32: rename CONFIG_SOC_STM32 -> CONFIG_SOC_FAMILY_STM32
Use CONFIG_SOC_FAMILY for the top level SoC family. A family
will have different SoCs or different SoC series with multiple
SoCs.
Adding the Family string to the config variable to avoid confusion
between actual SoCs and families and to prevent name collisions.

Maciek Borzecki 6461e70b72 gpio/stm32: add common driver for STM32 GPIO
The driver implements a GPIO device interface for STM32 MCUs. Each SoC
must provide implementation of the follwoing calls:
stm32_gpio_flags_to_conf(), stm32_gpio_configure(),
stm32_gpio_set(). Consult gpio_stm32.h header for details on semantics
of these calls.

The driver registers 5 devices, each corresponding to a single GPIO
port. The users can then access individual pins by using values
0-15.
