[PATCH 0/2] iio: adc: stm32-adc: add checks on adc state

[Olivier Moysan]

On ADC startup a calibration is launched.
A prerequisite for ADC calibration is to have ADC in disabled state.
After kernel boot, the ADC state may be unknown as the ADC may have been left enabled by boot stage.

Call ADC disable routine systematically before launching calibration.
Adapt ADC disable routine to perform disabling sequence according to current ADC state.

Olivier Moysan (2):
  iio: adc: stm32-adc: make safe adc disable
  iio: adc: stm32-adc: disable adc before calibration
