4 bool "Enable LED support"
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 "Enable LED support in SPL"
14 depends on SPL && SPL_DM
16 The LED subsystem adds a small amount of overhead to the image.
17 If this is acceptable and you have a need to use LEDs in SPL,
18 enable this option. You will need to enable device tree in SPL
22 bool "LED support for GPIO-connected LEDs"
23 depends on LED && DM_GPIO
25 Enable support for LEDs which are connected to GPIO lines. These
26 GPIOs may be on the SoC or some other device which provides GPIOs.
27 The GPIO driver must used driver model. LEDs are configured using
31 bool "LED support for GPIO-connected LEDs in SPL"
32 depends on SPL_LED && DM_GPIO
34 This option is an SPL-variant of the LED_GPIO option.
35 See the help of LED_GPIO for details.
