This series adds support for Low Power Timer that can be found on some STM32 devices. STM32 LPTimer (LPTIM) is a 16-bit timer that provides several functionalities. This series adds support for following features: - PWM output (with programmable prescaler, configurable polarity) - Trigger source for STM32 ADC or DAC (LPTIM_OUT) - Quadrature encoder and counter The MFD core is used to manage common resources (clock, register, reset) and to detect encoder feature. "stm32_lptimer" structure is provided to its sub-nodes to share those information: - PWM driver is used to implement single PWM channel - IIO trigger - IIO quadrature encoder and counter Fabrice Gasnier (8): dt-bindings: mfd: Add STM32 LPTimer binding mfd: Add STM32 LPTimer driver dt-bindings: pwm: Add STM32 LPTimer PWM binding pwm: Add STM32 LPTimer PWM driver dt-bindings: iio: Add STM32 LPTimer trigger binding iio: trigger: Add STM32 LPTimer trigger driver dt-bindings: iio: Add STM32 LPTimer quadrature encoder and counter iio: counter: Add support for STM32 LPTimer .../ABI/testing/sysfs-bus-iio-lptimer-stm32 | 57 +++ .../bindings/iio/counter/stm32-lptimer-cnt.txt | 25 ++ .../bindings/iio/timer/stm32-lptimer-trigger.txt | 21 ++ .../devicetree/bindings/mfd/stm32-lptimer.txt | 51 +++ .../devicetree/bindings/pwm/pwm-stm32-lp.txt | 24 ++ drivers/iio/counter/Kconfig | 9 + drivers/iio/counter/Makefile | 1 + drivers/iio/counter/stm32-lptimer-cnt.c | 382 +++++++++++++++++++++ drivers/iio/trigger/Kconfig | 11 + drivers/iio/trigger/Makefile | 1 + drivers/iio/trigger/stm32-lptimer-trigger.c | 110 ++++++ drivers/mfd/Kconfig | 15 + drivers/mfd/Makefile | 1 + drivers/mfd/stm32-lptimer.c | 110 ++++++ drivers/pwm/Kconfig | 10 + drivers/pwm/Makefile | 1 + drivers/pwm/pwm-stm32-lp.c | 216 ++++++++++++ include/linux/iio/timer/stm32-lptim-trigger.h | 24 ++ include/linux/mfd/stm32-lptimer.h | 55 +++ 19 files changed, 1124 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-lptimer-stm32 create mode 100644 Documentation/devicetree/bindings/iio/counter/stm32-lptimer-cnt.txt create mode 100644 Documentation/devicetree/bindings/iio/timer/stm32-lptimer-trigger.txt create mode 100644 Documentation/devicetree/bindings/mfd/stm32-lptimer.txt create mode 100644 Documentation/devicetree/bindings/pwm/pwm-stm32-lp.txt create mode 100644 drivers/iio/counter/stm32-lptimer-cnt.c create mode 100644 drivers/iio/trigger/stm32-lptimer-trigger.c create mode 100644 drivers/mfd/stm32-lptimer.c create mode 100644 drivers/pwm/pwm-stm32-lp.c create mode 100644 include/linux/iio/timer/stm32-lptim-trigger.h create mode 100644 include/linux/mfd/stm32-lptimer.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
