Unless I'm doing something wrong, I didn't get any warning with "make dtbs W=1". In fact many H3 boards have a node with this name and not a single warning is produced with this command for underscores (there are other warnings though). Actually, several H3 DT files have nodes like "sound_spdif" or "wifi_pwrseq". It seems like warnings are triggered only for children of soc node. > > > + compatible = "gpio-keys"; > > + > > + power { > > + label = "power"; > > IIRC the node name is used as a fallback when the label isn't there? Binding doesn't say anything about what happens if label is missing. Driver sets generic description "gpio_keys" in such case, which is not something that we want. Best regards, Jernej > > Maxime >

It looks like I've been remembering it wrong, and it's actually W=2 that reports it, but it's here nonetheless :) Maxime
