	  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.

	help
 | 
						|
	  Enable support for buttons which are connected to Analog to Digital
 | 
						|
	  Converter device. The ADC driver must use driver model. Buttons are
 | 
						|
	  configured using the device tree.

	help
 | 
						|
	  Enable support for buttons which are connected to GPIO lines. These
 | 
						|
	  GPIOs may be on the SoC or some other device which provides GPIOs.
 | 
						|
	  The GPIO driver must used driver model. Buttons are configured using
 | 
						|
	  the device tree.
