| help | |
| Many boards have buttons which can be used to change behaviour (reset, ...). | |
| U-Boot provides a uclass API to implement this feature. Button drivers | |
| can provide access to board-specific buttons. Use of the device tree | |
| for configuration is encouraged. | |
| config BUTTON_ADC | |
| bool "Button adc" | |
| depends on BUTTON | |
| help | |
| Enable support for buttons which are connected to Analog to Digital | |
| Converter device. The ADC driver must use driver model. Buttons are | |

| depends on DM_GPIO | |
| help | |
| Enable support for buttons which are connected to GPIO lines. These | |
