Main features are: - 16 fast GPIOs individually configurable in input/output - 8 alternate GPIOs individually configurable in input/output when other STMFX functions are not used - Main MCU IDD measurement - Resistive touchscreen controller Signed-off-by: Amelie Delaunay Signed-off-by: Lee Jones --- drivers/mfd/Kconfig | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'drivers/mfd/Kconfig') diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index 26ad6468d13a..87c55249dff2 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -1907,6 +1907,19 @@ config MFD_STPMIC1 To compile this driver as a module, choose M here: the module will be called stpmic1. +config MFD_STMFX + tristate "Support for STMicroelectronics Multi-Function eXpander (STMFX)" + depends on I2C + depends on OF || COMPILE_TEST + select MFD_CORE + select REGMAP_I2C + help + Support for the STMicroelectronics Multi-Function eXpander. + + This driver provides common support for accessing the device, + additional drivers must be enabled in order to use the functionality + of the device. + menu "Multimedia Capabilities Port drivers" depends on ARCH_SA1100 -- cgit
