Subject: [U-Boot] [PATCH 0/2] This series adds support for gpio-leds "default-state" property. The

From: Patrick Bruenn <p.bruenn@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.
