This series adds support for STM32F4 ADC into IIO framework. STM32F4 ADC is a 12-bit successive approximation analog-to-digital converter with multiplexed input channels. Conversions can be performed in single, continuous, scan or discontinuous mode. Conversions can be launched in software or using hardware triggers. This driver has been developed and tested on STM32F429 eval board. It consist of a core driver, to manage common resources shared between up to 3 ADC instances and an ADC driver to manage each adc instance. Changes in v3: - Core driver moved to iio/adc. - Build fix. - Updates following Jonathan's and Lars's remarks. - Binding: adc child clock is mandatory. Changes in v2: - Replace single driver model by MFD approach, to handle up to 3 ADCs as separate devices. Each ADC device then registers a unique IIO device. - Make driver as simple as possible for the first instance, to ease review. For now, I dropped complexity by removing injected support, triggered buffer mode, dmas. - Removed abstraction layer (indirection routines, ops) as only stm32f4 is supported.
