3config LED
4	bool "Enable LED support"
5	depends on DM
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.

12config SPL_LED
13	bool "Enable LED support in SPL"
14	depends on SPL && SPL_DM
15	help
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
19	  for this to work.

21config LED_GPIO
22	bool "LED support for GPIO-connected LEDs"
23	depends on LED && DM_GPIO
24	help
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
28	  the device tree.

30config SPL_LED_GPIO
31	bool "LED support for GPIO-connected LEDs in SPL"
32        depends on SPL_LED && DM_GPIO
33	help
34	  This option is an SPL-variant of the LED_GPIO option.
35	  See the help of LED_GPIO for details.
