From: Patrick Bruenn <p.bru...@beckhoff.com> main usecase in mind are LEDs which indicate a state like "power on". With this patchset applied, all you have to do is: Add a gpio-led node with 'default-state = "on";' property to your device tree. And the LED will automatically light up during U-Boot startup.
Changes in v2: - rebase to v2018.05-rc1 - add dm_test_led_default_state() to tests/dm/led.c Patrick Bruenn (3): dm: led: Support "default-state" property dm: led: auto probe() LEDs with "default-state" dm: led: add testcase for "default-state" property arch/sandbox/dts/test.dts | 12 ++++++++++++ drivers/led/led_gpio.c | 25 ++++++++++++++++++++++++- test/dm/led.c | 16 ++++++++++++++++ 3 files changed, 52 insertions(+), 1 deletion(-) -- 2.11.0 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
