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.

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.
