I added it because this driver took the veml6030 as a reference, and that driver provides the processed value. I guess that the veml6030 should have not provided processed values either, but it's late to remove them after the driver was released. Now that we are at it, what is the rule (of thumb?) to provide processed values? Those that can't be obtained from the raw data and simple operations with the scale/offset/integration time/whatever userspace can see? Thank you and best regards, Javier Carrasco
