config BUTTON
bool "Enable button support"
depends on DM
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
depends on ADC
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.
config BUTTON_GPIO
bool "Button gpio"
depends on BUTTON
depends on DM_GPIO
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.
config BUTTON_QCOM_PMIC
bool "Qualcomm power button"
depends on BUTTON
depends on PMIC_QCOM
help
Enable support for the power and "resin" (usually volume down) buttons
