| bool "Enable LED support" | |

| 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. | |
