New Revision: 280978
URL: https://svnweb.freebsd.org/changeset/base/280978
Log:
Handle multiple "gpio-leds"-compatible nodes
There are cases when gpioled nodes in DTS come from different sources
(e.g. standard Beaglebone Black LEDs in main DTS + shield LEDs in
overlay DTS) so instead of handling only first compatible node go
through all child nodes
