The STPMIC1 integrates 10 regulators ,3 switches, a watchdog and an input for a power on key. Signed-off-by: pascal paillet --- changes in v3: * Rename struct stpmic1_dev by struct stpmic1. * Rework i2c client data. * Clean device data structure content. The device data is used by MFD childs to access regmap. * Remove wakeup interrupt. * Reorder functions in order to remove prototypes. * Suppress static functions called from probe. * Cosmetics. drivers/mfd/Kconfig | 13 ++ drivers/mfd/Makefile | 1 + drivers/mfd/stpmic1.c | 401 ++++++++++++++++++++++++++++++++++++++++++++ include/linux/mfd/stpmic1.h | 212 +++++++++++++++++++++++ 4 files changed, 627 insertions(+) create mode 100644 drivers/mfd/stpmic1.c create mode 100644 include/linux/mfd/stpmic1.h diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index 11841f4..b8dabc7 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -1855,6 +1855,19 @@ config MFD_STM32_TIMERS for PWM and IIO Timer.
