This series adds support for STMicroelectronics Multi-Function eXpander
(STMFX) GPIO expander, used on some STM32 discovery and evaluation boards.
STMFX is an STM32L152 based I2C slave controller, whose firmware embeds an
I/O expansion feature, offering 24 GPIOs.
STMFX pinctrl/GPIO driver provides a GPIO interface supporting inputs and
outputs, and a pinctrl interface supporting push-pull and open-drain
configuration.
STMFX GPIO expander can also be used as interrupt controller.
Previous series [1], based on MFD and GPIO frameworks, is abandoned and
completely reworked.
