We don't have any at the moment. The way the bindings are currently defined (LED references are to individual LEDs for instance) are specific to LED bindings. I'd rather not make assumptions for e.g. Xenon flash devices. Which might never appear: LED luminosity, efficiency and maximum current has been steadily increasing over the past years. -- Regards, Sakari Ailus sakari.ai...@linux.intel.com
