You can submit a patch for leds/common.txt and a separate patch for the
adp1653 with a reference to the leds/common.txt for the child nodes.

- indicator-pattern : identifier of the blinking pattern for the
  		      indicator led; valid identifiers should be
		      defined in the documentation of the parent
		      node.

I wouldn't go for pre-defined identifiers as the pattern
can be a combination of various settings like ramp-up, ramp-down,
pulse time etc. Drivers should expose only few combinations of
these settings in my opinion, like e.g. leds-lm355x.c does.
