pinmux/stm32: add common driver for STM32 pinmux Add a common driver for pin control subsystem in STM32 MCU series. The driver allows for selection of pin's function without the ability of pin remapping. The driver implements a pinmux driver API, with custom `func` and `pin` encoding in API calls. The caller is expected to use STM32PIN() helper macro for encoding port/pin numbers or using one of the provided STM32_PIN_* defines. The common driver requires SoC specific support to be implemented. The SoC code must implement these calls: stm32_get_pin_config(), stm32_get_port_clock(), stm32_pin_configure(). Consult pinmux_stm32.h header for detailn on semantics of these calls. The driver also requires board level integration. The call stm32_board_get_pinconf() is expected to privide pin function assignments for the target board. Whenever an IO pin is being enabled, the driver will automatically enable the clock for corresponding port. The driver does not implement disabling of port's clock as this has potentially disruptive, as such such operation should be done explicitly in the code. The pin control module needs to be initialized before any other modules, but after clock_control. For this reason, the driver is initialized by default at PRIMARY level, with priority set to 2. The priority can be changed through configuration. Change-Id: I8cb746d0f3cad72cd50b3355fe6d93a9f469be25 Origin: Original Signed-off-by: Maciej Borzecki <maciek.borzecki@gmail.com>

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.

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.

help
This option controls the priority of pinmux device initialization.
Higher priority ensures that the device is initialized earlier in
the startup cycle. Note that the pinmux device needs to be initialized
after clock control device, but possibly before all other devices.
If unsure, leave at default value 2
