| 3 | help |
| 4 | This enables ADC API for drivers, which allows driving ADC features |
| 5 | by single and multi-channel methods for: |
| 6 | - start/stop/get data for conversion of a single-channel selected by |
| 7 | a number or multi-channels selected by a bitmask |
| 8 | - get data mask (ADC resolution) |
| 9 | ADC reference Voltage supply options: |
| 10 | - methods for get Vdd/Vss reference Voltage values with polarity |
| 11 | - support supply's phandle with auto-enable |
| 12 | - supply polarity setting in fdt |

| 54 | help |
| 55 | This enables driver for STMicroelectronics STM32 analog-to-digital |
| 56 | converter (ADC). |
| 57 | A STM32 ADC block can be composed of several individual ADCs. |
| 58 | Each has its own private registers, but shares some resources: |
| 59 | - clock selection and prescaler |
| 60 | - voltage reference |
| 61 | - common registers area. |
| 62 | STM32 ADC driver is composed of: |
| 63 | - core driver to deal with common resources |
| 64 | - child driver to deal with individual ADC resources (declare ADC |
| 65 | device and associated channels, start/stop conversions) |
