+STMicroelectronics STM32 ADC device driver
+
+STM32 ADC is a successive approximation analog-to-digital converter.
+It has several multiplexed input channels. Conversions can be performed
+in single, continuous, scan or discontinuous mode. Result of the ADC is
+stored in a left-aligned or right-aligned 32-bit data register.
+Conversions can be launched in software or using hardware triggers.
+
+The analog watchdog feature allows the application to detect if the input
+voltage goes beyond the user-defined, higher or lower thresholds.
+
+Each STM32 ADC block can have up to 3 ADC instances.
+
+Each instance supports two contexts to manage conversions, each one has its
+own configurable sequence and trigger:
+- regular conversion can be done in sequence, running in background
+- injected conversions have higher priority, and so have the ability to
+ interrupt regular conversion sequence (either triggered in SW or HW).
+ Regular sequence is resumed, in case it has been interrupted.
+
+Contents of a stm32 adc root node:
+-----------------------------------
+Required properties:
+- compatible: Should be "st,stm32f4-adc-core".
+- reg: Offset and length of the ADC block register set.
+- interrupts: Must contain the interrupt for ADC block.
+- clocks: Clock for the analog circuitry (common to all ADCs).
+- clock-names: Must be "adc".
+- interrupt-controller: Identifies the controller node as interrupt-parent
+- vref-supply: Phandle to the vref input analog reference voltage.
+- #interrupt-cells = <1>;
+- #address-cells = <1>;
+- #size-cells = <0>;
+
+Optional properties:
+- A pinctrl state named "default" for each ADC channel may be defined to set
+ inX ADC pins in mode of operation for analog input on external pin.
+
+Contents of a stm32 adc child node:
+-----------------------------------
+An ADC block node should contain at least one subnode, representing an
+ADC instance available on the machine.
+
+Required properties:
+- compatible: Should be "st,stm32f4-adc".
+- reg: Offset of ADC instance in ADC block (e.g. may be 0x0, 0x100, 0x200).
+- clocks: Input clock private to this ADC instance.
+- interrupt-parent: Phandle to the parent interrupt controller.
+- interrupts: IRQ Line for the ADC (e.g. may be 0 for adc@0, 1 for adc@100 or
+ 2 for adc@200).
+- st,adc-channels: List of single-ended channels muxed for this ADC.
+ It can have up to 16 channels, numbered from 0 to 15 (resp. for in0..in15).
+- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers" in
+ Documentation/devicetree/bindings/iio/iio-bindings.txt
