My only feedback is that in the other examples I found (common.yaml and leds-gpio.yaml), the children count off from 0 (e.g. led-0) instead of 1 as your series appears to. That's not a huge deal; it simply seems more consistent to count from the first index allowed by the regex (0). The patch is still fine, and so: Acked-by: Jeff LaBundy Kind regards, Jeff LaBundy
