This series adds support for the Azoteq IQS620A, IQS621, IQS622, IQS624 and IQS625 multi-function sensors. Each device integrates numerous sensing tech- nologies in a single package. A multi-function device (MFD) driver supports core functions common to all devices, including device identification, firmware, interrupt handling and runtime power management. The MFD driver is also responsible for adding all product-specific sub-devices. Each device supports self-capacitive, Hall-effect, and (in some cases) mutual- inductive sensing. These functions represent keys or switches and are supported by an input driver that covers all five devices. An assortment of pwm and iio drivers supports device-specific functions including ambient light and angular position sensing. This series was tested using the following development hardware: IQS620AEV04, IQS621EV04, IQS622EV04 and IQS624/5EV04. A demonstration of the series can be seen at the following link: https://youtu.be/7hJZPeFT0aY Jeff LaBundy (7): dt-bindings: Add bindings for Azoteq IQS620A/621/622/624/625 mfd: Add support for Azoteq IQS620A/621/622/624/625 input: keyboard: Add support for Azoteq IQS620A/621/622/624/625 pwm: Add support for Azoteq IQS620A PWM generator iio: temperature: Add support for Azoteq IQS620AT temperature sensor iio: light: Add support for Azoteq IQS621/622 ambient light sensors iio: position: Add support for Azoteq IQS624/625 angle sensors .../devicetree/bindings/input/iqs62x-keys.yaml | 132 +++ Documentation/devicetree/bindings/mfd/iqs62x.yaml | 179 ++++ .../devicetree/bindings/pwm/iqs620a-pwm.yaml | 32 + drivers/iio/Kconfig | 1 + drivers/iio/Makefile | 1 + drivers/iio/light/Kconfig | 10 + drivers/iio/light/Makefile | 1 + drivers/iio/light/iqs621-als.c | 617 ++++++++++++ drivers/iio/position/Kconfig | 19 + drivers/iio/position/Makefile | 7 + drivers/iio/position/iqs624-pos.c | 284 ++++++ drivers/iio/temperature/Kconfig | 10 + drivers/iio/temperature/Makefile | 1 + drivers/iio/temperature/iqs620at-temp.c | 97 ++ drivers/input/keyboard/Kconfig | 10 + drivers/input/keyboard/Makefile | 1 + drivers/input/keyboard/iqs62x-keys.c | 335 ++++++ drivers/mfd/Kconfig | 13 + drivers/mfd/Makefile | 1 + drivers/mfd/iqs62x.c | 1063 ++++++++++++++++++++ drivers/pwm/Kconfig | 10 + drivers/pwm/Makefile | 1 + drivers/pwm/pwm-iqs620a.c | 270 +++++ include/linux/mfd/iqs62x.h | 139 +++ 24 files changed, 3234 insertions(+) create mode 100644 Documentation/devicetree/bindings/input/iqs62x-keys.yaml create mode 100644 Documentation/devicetree/bindings/mfd/iqs62x.yaml create mode 100644 Documentation/devicetree/bindings/pwm/iqs620a-pwm.yaml create mode 100644 drivers/iio/light/iqs621-als.c create mode 100644 drivers/iio/position/Kconfig create mode 100644 drivers/iio/position/Makefile create mode 100644 drivers/iio/position/iqs624-pos.c create mode 100644 drivers/iio/temperature/iqs620at-temp.c create mode 100644 drivers/input/keyboard/iqs62x-keys.c create mode 100644 drivers/mfd/iqs62x.c create mode 100644 drivers/pwm/pwm-iqs620a.c create mode 100644 include/linux/mfd/iqs62x.h -- 2.7.4
