[PATCH 0/8] iio: adc: stm32-dfsdm: add buffer modes

[Fabrice Gasnier]

This patchset adds support for buffer modes, scan mode and triggers
in STM32 DFSDM ADC driver:
- 1st patch is an improvement
- Patch 2 to 5 are basically precursor patchs that reworks the way to
  configure the dfsdm for the audio part, so it can be common with the
  iio part.
- Last patchs add support for triggered buffer mode (with scan mode and
  hardware triggers)

Fabrice Gasnier (8):
  iio: adc: stm32-dfsdm: make spi_master_freq more accurate
  iio: adc: stm32-dfsdm: continuous mode depends on current mode
  iio: adc: stm32-dfsdm: move dma enable from start_conv() to
    start_dma()
  iio: adc: stm32-dfsdm: move dma slave config to start routine
  iio: adc: stm32-dfsdm: enable hw consumer
  iio: adc: stm32-dfsdm: add support for scan mode
  iio: adc: stm32-dfsdm: add support for buffer modes
  iio: adc: stm32-dfsdm: claim direct mode for raw read and settings
