But I do for my understanding. If I don't understand it, then my default answer is: no, we don't do "generic" bindings because the h/w is never generic. > If there are more than two LEDs that can be described by devicetree, > it can be an LED level meter by bundling them up with this binding. Depends on the physical locations too? If you just want to group any random LEDs, then do that from userspace because it's more flexible. Rob
