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 LED_BCM6328
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.

26 help
27 This option enables support for LEDs connected to the BCM6358
28 LED HW controller accessed via MMIO registers.
29 HW has no blinking capabilities and up to 32 LEDs can be controlled.

31config LED_BLINK
32 bool "Support LED blinking"
33 depends on LED
34 help
35 Some drivers can support automatic blinking of LEDs with a given
36 period, without needing timers or extra code to handle the timing.
37 This option enables support for this which adds slightly to the
38 code size.

40config SPL_LED
41 bool "Enable LED support in SPL"
42 depends on SPL && SPL_DM
43 help
44 The LED subsystem adds a small amount of overhead to the image.
45 If this is acceptable and you have a need to use LEDs in SPL,
46 enable this option. You will need to enable device tree in SPL
47 for this to work.

52 help
53 Enable support for LEDs which are connected to GPIO lines. These
54 GPIOs may be on the SoC or some other device which provides GPIOs.
55 The GPIO driver must used driver model. LEDs are configured using
56 the device tree.
