6 | help | |
7 | Many boards have LEDs which can be used to signal status or alerts. | |
8 | U-Boot provides a uclass API to implement this feature. LED drivers | |
9 | can provide access to board-specific LEDs. Use of the device tree | |
10 | for configuration is encouraged. | |

13 | bool "LED Support for BCM6328" | |
14 | depends on LED && ARCH_BMIPS | |
15 | help | |
16 | This option enables support for LEDs connected to the BCM6328 | |
17 | LED HW controller accessed via MMIO registers. | |
18 | HW blinking is supported and up to 24 LEDs can be controlled. | |
19 | All LEDs can blink at the same time but the delay is shared, which | |
20 | means that if one LED is set to blink at 100ms and then a different | |
21 | LED is set to blink at 200ms, both will blink at 200ms. | |

63 | Some drivers can support automatic blinking of LEDs with a given | |
64 | period, without needing timers or extra code to handle the timing. | |
65 | This option enables support for this which adds slightly to the | |
66 | code size. | |

71 | help |
72 | The LED subsystem adds a small amount of overhead to the image. | |
73 | If this is acceptable and you have a need to use LEDs in SPL, | |
74 | enable this option. You will need to enable device tree in SPL | |
75 | for this to work. | |
