[PATCH 00/10] Add support for STM32 ADC

[Fabrice Gasnier]

This series adds support for STM32F4 ADC into IIO framework.
STM32F4 ADC is a 12-bit successive approximation analog-to-digital
converter. It has up to 19 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 ease support for other STM32 family
ADCs, and a specific driver for STM32F4 ADC.
It allows to use direct or triggered buffer modes with triggers.
Optional support for DMA and few extended attributes is included.
