- menu "LED Support"
- config LED
- bool "Enable LED support"
- depends on DM
- help
- Many boards have LEDs which can be used to signal status or alerts.
- U-Boot provides a uclass API to implement this feature. LED drivers
- can provide access to board-specific LEDs. Use of the device tree
- for configuration is encouraged.
- config SPL_LED
- bool "Enable LED support in SPL"
- depends on SPL && SPL_DM
- help
- The LED subsystem adds a small amount of overhead to the image.
- If this is acceptable and you have a need to use LEDs in SPL,
- enable this option. You will need to enable device tree in SPL
- for this to work.
- config LED_GPIO
- bool "LED support for GPIO-connected LEDs"
- depends on LED && DM_GPIO
- help
- Enable support for LEDs 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. LEDs are configured using
- the device tree.
- config SPL_LED_GPIO
- bool "LED support for GPIO-connected LEDs in SPL"
- depends on SPL_LED && DM_GPIO
- help
- This option is an SPL-variant of the LED_GPIO option.
- See the help of LED_GPIO for details.
