| 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 LED_BLINK |
| bool "Support LED blinking" |
| depends on LED |
| help |
| Some drivers can support automatic blinking of LEDs with a given |
| period, without needing timers or extra code to handle the timing. |
| This option enables support for this which adds slightly to the |
| code size. |
| |
| 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" |
