    Subject[PATCH v2 0/7] Introduce STMFX I2C Multi-Function eXpander
    Date
    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 a pinctrl MFD child.

    ---
    Changes in v2:
    - move to MFD parent driver for i2c stuff and chip initialization
    - improve regmap configuration
    - take advantage of the use of gpio-ranges


    Amelie Delaunay (7):
    dt-bindings: mfd: Add ST Multi-Function eXpander (STMFX) core bindings
    mfd: Add ST Multi-Function eXpander (STMFX) core driver
    dt-bindings: pinctrl: document the STMFX pinctrl bindings
    pinctrl: Add STMFX GPIO expander Pinctrl/GPIO driver
    ARM: dts: stm32: add STMFX support on stm32746g-eval
    ARM: dts: stm32: add joystick support on stm32746g-eval
    ARM: dts: stm32: add orange and blue leds on stm32746g-eval
