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.

|
|
GPIOs may be on the SoC or some other device which provides GPIOs.

The GPIO driver must used driver model. Buttons are configured using
