I welcome patches that add schemas for the undocumented compatibles instead. Otherwise, I will be turning on this check by default and nagging people to fix them. > This removes the information on how to use the bindings. Surely we > prefer to over document rather than under document? How is what the 'gfx' and 'lpc' nodes contain relevant to how the pinctrl binding works? If a user wants to know, then they should go look at the aspeed,ast2500-lpc/aspeed,ast2500-gfx bindings and their examples. Which brings up my secondary issue which is having the same example multiple times. It is multiple chances for errors (that I end up fixing). How do we know the example is even correct without any schema checks? The 'framebuffer' node is not in a valid location is the most obvious thing I see. Rob

Surely we > prefer to over document rather than under document? There is no need to document consumers of generic providers, like syscon, clock or pinctrl. These are already well documented. The examples of consumers here do not bring any additional value. Best regards, Krzysztof

Concerns about lost examples can be solved with incremental patches on top adding more schema. Yours, Linus Walleij

The additional nodes in the example referenced from the pinctrl node 'aspeed,external-nodes' properties are either incorrect (aspeed,ast2500-lpc) or not documented with a schema (aspeed,ast2500-gfx). There's no need to show these nodes as part of the pinctrl example, so just remove them.
