The following patches add support for triggered buffer mode.
These are based on top of "Add PWM and IIO timer drivers for STM32"
series. Reference:
https://lkml.org/lkml/2017/1/20/116

STM32 ADC, can use either interrupts or DMA to collect data.
Either timer trigger output (TRGO) or PWM can be used as trigger source.
This patchset has been tested on STM32F429 eval board.

Fabrice Gasnier (7):
  iio: adc: stm32: add support for triggered buffer mode
  iio: adc: stm32: Enable use of stm32 timer triggers
  iio: adc: stm32: add trigger polarity extended attribute
  Documentation: dt: iio: stm32-adc: optional dma support
  iio: adc: stm32: add optional dma support
  ARM: dts: stm32: Enable dma by default on stm32f4 adc
  ARM: dts: stm32: Enable pwm1 and pwm3 on stm32f429i-eval

Patches 6 & 7 (DT) applied on stm32-dt-for-v4.12
