Driver is embedded upon CFG_STM32_GPIO=y.
STM32 GPIO driver API main functions:
- stm32_gpio_set_output_level() sets target output GPIO level,
- stm32_gpio_get_input_level() returns target input GPIO level,
- stm32_pinctrl_load_active_cfg() loads interface pin mux active state,
- stm32_pinctrl_load_standby_cfg() loads interface pin mux standby state,
- stm32_pinctrl_fdt_get_pinctrl() save pin configuration from DT content,
- stm32_gpio_set_secure_cfg() sets secure state for target GPIO/pin mux.
GPIO driver does not register to PM framework. It is the GPIO/pin owner
responsibility to call stm32_pinctrl_load_{active|standby}_cfg() on
peripherals power state transitions.
