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. --- Changes in v5: - mfd: fix Lee's comments (reorder struct declaration, drop mfd cells platform data initialization, typos) - pinctrl: get stmfx struct through dev_get_drvdata(pdev->dev.parent) instead of dev_get_platdata(&pdev->dev); Changes in v4: - mfd: move registers #define into the header - mfd: merge stmfx and stmfx_ddata structures into one stmfx structure - mfd: change stmfx_chip_init/exit and stmfx_irq_init/exit args: use i2c_client struct and i2c_get_clientdata - mfd: fix typos - mfd: add MFD cells for IDD and TS features - pinctrl: rework registers #define - dts: add STMFX support on stm32mp157c-ev1 Changes in v3: - fix MFD interrupt bindings - fix drivers/mfd/stmfx.c:103:8: warning: 'mask' may be used uninitialized in this function 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 (9): 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 ARM: dts: stm32: add STMFX support on stm32mp157c-ev1 ARM: dts: stm32: add joystick support on stm32mp157c-ev1 Documentation/devicetree/bindings/mfd/stmfx.txt | 28 + .../devicetree/bindings/pinctrl/pinctrl-stmfx.txt | 116 +++ arch/arm/boot/dts/stm32746g-eval.dts | 66 ++ arch/arm/boot/dts/stm32mp157c-ev1.dts | 60 ++ drivers/mfd/Kconfig | 13 + drivers/mfd/Makefile | 2 +- drivers/mfd/stmfx.c | 566 ++++++++++++++ drivers/pinctrl/Kconfig | 12 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-stmfx.c | 820 +++++++++++++++++++++ include/linux/mfd/stmfx.h | 123 ++++ 11 files changed, 1806 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/mfd/stmfx.txt create mode 100644 Documentation/devicetree/bindings/pinctrl/pinctrl-stmfx.txt create mode 100644 drivers/mfd/stmfx.c create mode 100644 drivers/pinctrl/pinctrl-stmfx.c create mode 100644 include/linux/mfd/stmfx.h -- 2.7.4
