Hi, > I don't follow. Can't you just use 'status = "disabled;"' for the > unavailable nodes? Sure but unless im missing something, adding some nodes to a dts, one for eatch led the device in question really has feals mutch better to me than going arround and setting every led channel disabled for eatch device that dosent use it. xt894 being the outlier here amoung the cpcap devices we intend to support (xt894, xt860, xt875, xt910, xt912, mb865, mz609 and mz617) in that it uses most of the extra led channels, most of these use at most one (xt875, xt910, xt912, mb865) or zero (mz609, mz617) extra channels.
