This series adds support for STMicroelectronics Multi-Function eXpander
(STMFX), used on some STM32 discovery and evaluation boards.
STMFX is an STM32L152 slave controller whose firmware embeds the following
features:
- I/O expander (16 GPIOs + 8 extra if the other features are not enabled),
- resistive touchscreen controller,
- IDD measurement.
I2C stuff and chip initialization is based on an MFD parent driver, which
registers STMFX features MFD children.
